I was on the phone with a distributer because i was interested in a set of next valve springs for my cam swap. He stated that since my cam was a 588 lift cam to go with a 600 lift spring which is fine. But he said that the springs wont work because i would need to have the seats milled down to accept the 600 springs. I have never heard this at all with all the cam swaps ive read on this board. It does make sense to do it, but im not tearing off stock heads just to have them milled and throwing them back on. Ill just opt for a new set of aftermarket heads. Man this throws a wrench in my cam only swap. Whats your guys\gals imput on this? Jay
