Porting small block 915 j-heads

Please let me know


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.

I have seen that sort of thing in some Super Stock Hemi heads 20 yrs ago... the details are a little foggy, but they abandoned it cause they didn't want any of the epoxy coming loose at 8000 rpm.:eek:
