Thank you one and all for sharing your knowledge. This bunch of racers has more experiential knowledge of what works and what doesn't than any body else could imagine. I got the heads down to bare castings,the intakes all look great, all but two of the exhaust seats need help. I plan to reface them , lightly touch the valves, new seals, and new springs. Now, with a 327,250 horse, 1.72 intakes,1.500 exhausts, Elgin rockers, not rollers yet, new Comp springs,what spring tension should I go for?I was thinking 350 over the nose, 180 on the seat. This engine is done by 7000,so i wasn't going for broke on the spring pressures.If it was a 275 horse with roller rockers, that would be different. This engine does have a steel Bullet cam and Smith lifters. Wouldn't it be great if we could run a rev kit on a stocker motor? Just thinking.
