LS6 heads to AFR heads?
I'm currently putting together a forged 347 with a 235/243 .621”/.624” 111LSA +4 advance cam. My current mods are milled 61cc PRC LS6 heads, 90/90 fast, 1 ¾in longtubes, and 9in 3.89”S. I’m adding a UD pulley and YT rockers. My last cam was a MS3. Right now I might have the opportunity to pick up a set of 62cc AFR 205’s. The question I have is how much a benefit I would have to switching from my current heads? My CR sits at 11.2:1 with a set of .040 cometics and my -2cc pistons with the PRC’s. With the 205’s it would go to 11.06:1 so I would probably mill them to 61cc like my PRC’s. I just don’t want to spend the money if it’s not going to be that great of difference. Any help and opinions would be greatly appreciated.
