Yella Terra full roller rocker q's

[matt1967]

I'm going to go with the Yella Terra full roller rockers on my 200 I6 Turbo build, I know how the oil thru pushrods work but how is the oil redirected to the lifters and not come out the stock passages? do I need to machine anything?

Matt, the stock oil supply from the previous rear rocker shaft is blocked off by the plate supplied with the full roller rockers.

Since you have to use small block ford oil through lifters all the rockers are supplied via the lifters with the supplied hollow pushrods.

The full roller rockers are the only way to go if you want that last 10-15HP because of the 1.65 rocker ratio & less friction with fully rollerized valve train. William

William is exactly correct.
Just make sure you have the correct lifters. If they don't have a little hole where the pushrod meets the lifter then you need to change them out for "oiling lifters".
Later,

I had been wondering but.....

if running the full rollers would there be a benifit to running an oil spray bar on the valves/springs? seems you could have an oil supply available under the rocker cover for this.

I would think that the only benefit would be to cool the springs a bit.
But the increased quantity of oil in the valvecover wouldn't be good.
It might decrease the pressure and quantity of oil for the mains.

I believe there are a number of engines oiling trough the pushrods and don't starve the mains, if they did I'm sure a restictor of sorts could be fashioned.

Sorry guys but the Terra rockers don't seem to be available in the USA anymore, Mike has been trying to get me a set for months, seems the demand just isn't there for them to make them and/or ship them to a small busness like Mikes, althought the roller tipped is avalible from Mike. I am in the process of making my own set of full roller rockers, if it all works out right, I might make some sets for other people, this will take weeks to get right I'll let you know how things come out.

so they dont make them anymore?
