We checked pushrod length like 40 times with a comp cams pushrod checker. The pushrods that are in this motor are the ones that are supposed to work with it. The only way to get the roller tip of the rocker to sit correctly on the valve stem is to use a 6.950 push rod but if you use that long of a pushrod there are not enough threads left to lock down the poly lock. We then measured from the center of the screw in stud to the center of the valve guide and they are all out of whack. Some of them are not even straight. The problem is the valve or screw in stud is to far apart so the rockers don't sit on the valve stem correctly. I even tried putting a set of SBC rockers on it since they are a little longer from the roller tip to the fulcrum and they did fit a little better but were not perfect.

I have said this 30 times and will say it again, Push rods are not the problem.

 

josh good luck with what ever you choose

 

where safety glasses at all times watch out 4 flying pushrods youll poke your eye out kid jfwy again bump for killer price on parts

 

wheres that, I need goggles guy!!!!! Or whatever his screen name is , he was a funny troll...oops I mean funny dood!!

So what are they good for paper weight? Anchor?


And let's not forget - Header Fitment, Valve Cover Fitment, and Spark Plug Fitment as well.......

 

Shaun, you and I both know that we tried to get the measurements on the pushrods to be the reason. If I thought it were that simple of a fix, I'd probably try to keep them myself - but I was pretty sure we ruled that out

John (Tiffiny), and 97305Cobra, and Jay Allen seem to think differently - but by all means - if they'd like to buy the combo and try a different pushrod to try to make it work - who am I to stop them?!

Raymond - to me, they're nothing more than a lost cause on my setup. However, for someone who has machinist experience, or a close relationship to someone at a machine shop... I think these heads could be cleaned up and made right for someone fairly inexpensively. I have none of that knowledge, nor connections at a machine shop, nor do I have the patience to attempt anything further on these heads

 

I actually have a set of them on a customer car. They work fine but have rocker noise like they are solid lifters and it can not be adjusted out. Promts for you for telling the truth about them.

 

Stewart Scott has the same noise with his heads.

 

good luck josh.

 

I need it bro
