360 J heads porting info

Heeeeey, cool man. Thanks.I have a set of J's with 2.02/1.60's. I have had these things for a long time. About ...crud..22 years now.
Those numbers aren't to bad for stock OOTB head, or should I say On & Off The Block
He he he.
Thanks Terry.

In that case, a few trick works and they should do well. Back cut valves, gasket matching and a bowl blending. I can see a mean pick up.
