If you go forward on heads in the future, i had found this tidbit that most don't appear to notice. Our heads, even after being "setup properly" by vendors typically aren't 100% correct. We use LS springs that require an install height of 1.800", modded retainers only give us 1.78X" ....therefore the spring seats should be machined to ensure all aspects (spring height to specs of springs being used, valve guide machined to accomodate expected lift plus seal plus a little insurance space) are good. I think I got lucky that I wanted the shop to check stuff and they noticed the seats.

Funni thing is when i brought the heads to the shop.. The machine laughed and said no way in hell those are cleared for over 600. Lift by just looking at them .. Showed me some heads he just finished porting (aluminium by the way).... And made me wish i had never grabbed the heads i had smh..they are ported... he spoke but not to the intent to compliment the cam after i showed him the cam specs..
