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

Re: 1.6 roller 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
Re: 1.6 roller rockers????
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.
