512 B1 heads HP?

[famous bob]

Tell me about it. Making holes bigger for 7/16 pushrods and a 1.7 rocker. I must have test fit them 4-5 times.

Like I posted , "took me 4 times" in the car, and only 3/8'' pushrods ! That was enough for me , course it would have been easier on the engine stand had I caught it .
First wedge I`d ever built. Hemi`s and sbc way easier to work on !
