1.6 roller rockers????
Who, or how many out there are running 1.6 roller rockers on their TPI 350, with NO HEAD MODIFICATIONS??? Has anyone had pushrod clearance issues??? Thanks for any replies to this....Tom

I have the GM aluminum 1.6 roller rockers on stock 305 heads and stock valve covers. No issues. They are a bit noiser than the original stamped steel rockers.

I seem to have a clearance issue where the pushrods go thru the heads, does anyone know what is a safe amount of clearance????? Thanks, Tom

I dont have a number for clearance, but if you are running the stock heads, you need self-aligning rocker arms and that takes care of the clearance issue. I know there isnt a lot of clearance on my 305 heads, but no problems with the self-aligning rockers.
