New 408 build finally started
I’m going to assume the problem is....... if you try and relieve the head more to allow the pushrod to work with the .350 offset rocker...... you’ll break through into the intake runner?
I always assumed the Hughes Bigmouth porting retained the std port opening size(or close to it).
You’ve clearly moved the pushrod side wall,at the port opening, over beyond how the BM heads are.
You’ve moved the wall over farther, so you’re going to need more offset.
