valve stem height - need some help

Have u taken into consideration that u need .600-.630 offset intake rocker arms.

I did not think of this, and thanks. Good point and I bet you are right.

If the 265’s are what he has, I’d look into sending them back and buying some Stealth heads instead.

These are the 265cc version, so between an inappropriate head and the valve stems being goofed up, I am returning them. I will chalk this episode up to good intentions but not enough research to ensure I order the right parts. I will work on this project moving forward, with more input to best parts to order.

Many thanks to all who helped out on this - I keep learning, even if it's the hard way sometimes.
