Anyone running 5.3L heads?
I am thinking of hand porting a set of 5.3L heads. I did a search, but did not turn up too much. Anyone know where you can pick up bare heads cheap? Any input would be appreciated.

there are TONS of fbodies running the truck heads.....
they will bolt right on, and you get a boost in compression with them as well (not sure how much but ya do)
not much info, but hope that helps

Stock, the 5.3's flow like stock LS1's, but give more compression on a 5.7. The MMS Stage II X heads are based on the 5.3's, but milled for more compression (11.2-11.4:1). I love the results I have gotten with mine. :cheers:

We use the 5.3 casting for our CNC ported heads on N/A vehicles. We use the 5.7 on supercharged vehicles. The 5.3 is a great head. You need to open the chamber to unshroud the valves , particularly when going to a 2.02 intake.

Thanks for the info guys! especially Andy@A&A. I wondered about the valve shrouding with a small chamber.
I think I'll do a set this winter. :smash:

Check the recent thread by C5Noir. He and I are both getting ready to install our TEA 5.3L stage 2 heads. TEA produces some excellent flow #'s and builds the heads to be on the money the first time around.
Good luck w/ your decision! :cheers:
