Question: Hey Richard, what are the “BEST” stock heads for a turbo LS? Answer: The ones you have on the motor! ANY set of stock cylinder heads can make 1000 hp with the right turbo! You don’t need ported or aftermarket heads (thicker decks do help sealing though) to reach 1000 hp! Run what the junkyard brung!

LS3 Intake on Cath Port Heads With Adapters! The LS3 intake is arguably the best factory GM intake ever made, but does it work with cath-rec port adapters used for LSA blower installs? Anyone else ever tried or tested this? The answer is it will bolt on, but the LS3 intake with adapters makes less power (by 18 hp) than just running a TBSS or Dorman LS2. I wanted this to work so bad back in 2018 when I tested it, but it just didn’t pan out. Get a cath port intake! Make sure to check out the sales

Can you run factory big-valve, rec port, LS3 style heads on a small-bore, 4.8L/5.3L motor? Using my cut-away alum block from ATK (thnx Mark Sanchez), I illustrated the massive interference. The valves (intake and exhaust) hit the edges of the small bore cylinders. Even grinding reliefs didn’t work. Don’t fear, there are small bore rec port heads available, the question for me would be, are they necessary when ported stock or after market cath-port heads (like @afr_heads) flow over 300 cfm? Do yo
