Valve adjusting?

[Anonymous]

hey guys,


i had some extra time on my hands today so i finished building my spare head. I ported and polished the intake and exhaust, did a 3 angle valve job, and rebuilt the rocker assembly. Now i know this is a stupid question but how do you adjust your valves or how do i check to see if they need adjusted. Thanks a bunch

Wes, is the head in the car? That's the only way to adjust.

Those are the best instructions I've found...it's a few pages down, on like 412 (you start on 408 with that link)

Disconnect the coil wire first for safety, making sure the motor won't accidentally start. Some guys prefer to remove all the plugs too, so that the engine is easier to rotate during the procedure. Make sure to mark your plug wires so you don't mix up the firing order when reinstalling them.

Next rotate the engine until the number one (#1) cylinder is on TDC just after the compression stroke. Now you can adjust the following valves: #1 intake - #1 exhaust - #2 intake - #3 exhaust - #4 intake - #5 exhaust

Next, rotate the engine until the number six (#6) cylinder is on TDC just after its compression stroke (one full revolution of the crank shaft). Now adjust the remainder of the valves: #2 exhaust - #3 intake - #4 exhaust - #5 intake - #6 intake - #6 exhaust

Adjust the valves by backing off the adjuster so that the pushrod can be easily rotated between your thumb and forefinger. Then slowly tighten the adjuster until you can no longer rotate the pushrod. Tighten the adjuster an additional ¼ turn, for the proper preload.

Note: The valve adjustments should be done on an engine that has been warmed up. Make sure to let it cool off sufficiently so that you don't burn your fingers while rotating the pushrods. It is also a good idea to place a drop cloth or oil pan under the car/engine to prevent oil drips on the floor.

I suppose you could check and adjust the valve spring tension with spacers. I've never done this yet. I assume the guy who rebuilt my head, did it.

okay i feel stupid...


do i still adjust the valves even though im using the stock rockers and rocker shaft assembly

Anytime you pull the head, it's worth it to readjust the valves. It only takes about 20-30 minutes for your first time. When you do it a few times, only takes about 15 minutes.

I've seen heads from three local workshops and only one ever shimmed the springs. It's coincidentally my preferred place.
