Having seen a few bad sets and warned by a few who build motors and heads for a living of the pitfalls. It was recommended to me by someone who builds some of the fastest heads in the world that if weight wasn't a concern the race series head was the way to go. For those reasons I have steered clear of them.

What I meant by the geometry problem was a generalized statement not directed towards a pro 1 head. But a BBC in general.

You should see the geometry on some of AFR"s bbc heads. Particularly the intake rocker stud to valve distance. Nothing a .090 backset rocker arm couldnt help though. Now, with a scorpion rocker or comp rocker, perfect pushrod length, the roller tip would be nearly on the retainer, rather than the valve stem. But supposedly they fixed that.

I can't find anything wrong with the head. The lock nuts are all the exact same height ( straight edge straight ) The boss is perfect. I don't for the life of me know why there is this pattern on the bottom of the valve cover. Looking at the cover that is a low spot in the face of the cover. There are other marks on the cover but none as pronounced as this one. Nothing seams broken here.

Tink, what rocker studs are in those heads? Just wondering why the intake poly set screws, are sunk quite a bit down in the lock, where the exhaust, not so much. How much thread engagement did you have on those intake studs???

Obviously you have no reading comprehension. Please read and re-read post #20 and maybe you will get it on your own. I may have some bullchit coming out of my mouth but obviously you have diarrhea of the brain.

I read Post #20 and you can take i both ways.
I took it first as any motor with rocker arms has a geometry problem.
But, re reading it, I can see it the other way.
So, your both right and wrong.
Miscommunication thru typing at it's finest.
Move on.
