Porting small block 915 j-heads

I don't think so....
I've got to do a set of BBM heads this week.. I will make a point to epoxy guide to a point, like that, so see if the bench likes it or not.

I would say the most scienced out heads I’ve worked on were the SBC 18* heads that came off the Busch motors.

No sharp edges.

I don’t put sharp edges on the leading edges....... but not for concerns of air flow(although, I don’t think a pointed leading edge is fundamentally correct from an aerodynamic standpoint).

Maybe it’s not too late to make them less sharp if it turns out 63GT:s bench doesn’t like it.
From what I’ve learned so far is that experience and equipment is a VERY good thing to have.
Shape , flow test , reshape , flowtest again , pitot tubes , flowballs , the sound of a port and so on and on and on.
Everything is experience and testing.
