I am rebuilding a 1968 200 with a 69 M head. I have searched for many hours and can not find new stock valve springs. Sealed power lists vs624 as a stock replacement but no one has them that I could find and the one vender said they are discontinued. I am looking for a spring that duplicates the stock open and close pressures with a maximum of 60 seat and ~150 to 180 open. The cam is a Schneider 256H with a lift of 0.420. The lowest spring Schneider has puts the closing pressure at 147 with a height of 1.59, way to high. Schneider said that the stock springs will work with that cam.
My question is what are others using for valve springs?
Thanks

You might be also be able to find some NOS stock 200 Six Valve Springs at one of the Antique Ford Parts Houses. I used to look at CW Moss in Orange Calif for those old Falcon parts but looks like they have discontinued that parts line quite sometime back, maybe try at Mac's Auto Parts.
 
My question was too vague.
302 valve springs:
I found 5 springs listed for 302 springs and all are different. Our classic inline tech lists springs with part numbers but the numbers do not exist. I would like to get the spring rate and open and close pressures at specific lifts. I finally found a Melling spring chart where I can calculate the actual open and close pressures at the specific closing spring height of 1.59 inches which is the actual spring close height.

Melling spring vs870 works good until we check coil bind 1.59-0.420 (valve lift for 256H cam) =1.170. Coil bind is 1.150, to close.

One must calculate actual pressures at install and open heights and then check for coil bind. Once a good spring is picked we then must see if it is available.

I am going to use the springs I have for now. They came on the M head. I measured the pressure at installed and open height and I get 50 @1.59 and 155 at 1.170. Coil bind is 0.960. They are painted red. I can always shim if need slightly more.

Thanks

This spring will be about 70 lbs on the seat and 165 open which will work fine with the Schneider 256H camshaft.

The stock Small Six Valve Springs will allow Valve Float at around 4500 RPM. These were the Performance 289 & 302 Valve Springs that Classic Inline listed & recommended, Clay Smith probably was the supplier for them though there doesn't seem to be a listing for them now.

They Recommended the HiPo 289 Single Valve Springs set of 12 SSI-289-SPG even for use with the stock Camshafts.
Spec's Closed Pressure 60 lbs., Open Pressure 175 lbs., Installed Height of 1.680" on a Cast Iron Head & on an Aluminum Head the installed Height is 1.600", Coil Bind .530, for use with Camshaft Duration's of up to 260 Degrees. These were a good upgrade for Daily Driver Street use on a stock or mildly Cam'ed engine that aren't Revved over 5000 RPM. Can be used with the Standard Ford Umbrella Valve Seals or with Viton .530 Valve Seals.

Next step up was the Single 302 Valve Spring set of 12 SSI-302-SPG
Spec's Closed Pressure 80 lbs., Open Pressure 200 lbs., Installed Height of 1.680" on a Cast Iron Head & on an Aluminum Head the installed Height is 1.600", Coil Bind .480, used for Camshaft Duration's of up to 270 Degrees. Good for Street or Performance use on mildly built engines that aren't Revved over 5500 RPM or occasionally to a max of 6000 RPM, can be used with the Standard Ford Umbrella Valve Seals or with Viton .530 Valve Seals.

The installed heights of the springs you listed are too high.
The installed height is 1.59” for this head making the V8 spring seat pressures way too high if installed at 1.59”

Yes your right pmuller9 thank you for catching that if springs are to be set up on an Aluminum Head than use the 1.590 to 1.600" installed height. I got all those spring install heights and all the other specs from the old Classic Inlines source with their spring numbers when used on the Ford Small Six Heads. The 1.680 is the height they list for the Cast Iron Heads though, I just now added the install height on my above post to correct the Info so it will be right for both the Cast Iron Heads and the Aluminum Small Six Heads when used on the 144, 170, 200, or 250 Six's. I will be setting up a Large Log Big Valve Head and will be doing a Custom Tri Power install and setup soon so I can also verify all this as far as the cast iron heads go. Edited
 
Most springs are pressure rated at two heights, open and closed. The spring pressure/height function is more or less linear over the usable ranges. You can use the two rated points to set up a line on a graph to see what the spring pressure would be at a slightly different height. A spring that fits fairly well and is just a little stiffer than the stock spring but softer than the V8 springs (yea, which one of many?) is the 240 police/taxi exhaust valve spring.
 
After checking my spring height/pressure graph/worksheet, I've got some numbers for the 240 Police/Taxi exhaust valve springs I mentioned earlier. Using the thinner one piece early 260 valve retainers for an installed height of approximately 1.640", the closed spring pressure would be about 64 pounds. A lift of .420" yields a 1.220" open height, with a pressure of around 181 pounds. The coil bind height for these springs is 1.12", so that seems like a sufficient margin. Not exactly what you were looking for but pretty close. But your basic problem was availability, and I haven't looked to see if these can be found, so I might just be wasting your time. Sorry. I got mine NOS on ebay.

You can always have the spring pocket cut to change your installed height.

Somewhere on the site is a picture of a Log Head that site member "wsa111" posted, the head was band sawed to show the Valve Spring Pocket Depth and Intake Log and Port Thickness, there is very little material there so for myself I wouldn't recommend that you do much if any machining there. Going to longer Valves or some Offset Valve Keepers would be better way to go depending on how much more install height you need for the Valve Springs. Best of Luck
 
I had 0.10" cut in the spring pockets and run heavy springs, never had a problem. Cast iron is pretty tough. Now the Alum head, I wouldn't. in fact after my problems with the Alum head, I wouldn't cut on it at all.
 
The Crower spring 68147-12 looks perfect. Now the availability. Jegs says 10-11 if available at manufacturer, Summit says shipping in January of 23, so who to believe. I will call Jegs and see what is up.

I appreciate all the responses - Thanks
 
Yes the Crower spring 68147-12 is a good match, Thanks pmuller9. So I called Crower and they do not have any in stock and do not plan on having them in the future. Jegs has 16 single springs in stock at 7.99 each for a total of $96.00. The -12 is $52.00. Called Jegs, they will not give me 12 for the priced of the 12 pack. They also do not have the retainers that go with the springs.
Who said this was easy!
