360 J heads porting info

In this case, I'm experimenting with the KB236 quench dome pistons. They are for use with open chamber heads. I'm just seeing if it's worth the extra setup time to run the psitons, so I'm obligated to using the heads. I am not a millionaire as some might be inclined to accuse me of, but I dont shrink away from spending the money on what I know I need. I also did ream the shop a little because the bill surprised me...lol. Truthfully, Edelbrocks are a great head. But I've handled enough to know there's no way I will bolt them on and run them. So you have the initial cost and shipping $1300-1400. Then the valve job to fix them $250, then the springs I need for the cam I want to run (edelbrock springs will work for max lift, but they dont have the tension I need..many times that is the case with fast rate cams..they dont tell you that tho. Edelbrock just says "to .600 lift...") So really, to have them bolt on, I would have been looking at around $1600 to have them really ready to bolt on. As for me, I built 6 engines last year. 2 418s, a 496, 1 383 and 2 440s. Of those 6, 3 had aluminum heads. The 3 with stroker cranks. The others either didnt want them, or didnt need them, or both. I'm one for being honest, and I wont upsell if the customer doesnt need them to make the requested goal. But I have no qualms about paying to get good work and parts. "You can pay more to do it right once, or you can pay once, then pay more to do it right the second time."
