Lifting heads at 19 psi?

[George C]

are you a tuner? are you a builder? do you have any actual turbo experience with them?


point being answers are NO, any head on market can push coolant in the wrong hands. Look at Kurt last he reported he was using the L92 heads and over 1100 rwhp and hasnt reported pushing water. and the deck thickness difference between the 317s and Ls3 bunch is roughly 1/16th of an inch that isnt enough to really create big issues. its rumors ppl picked up and followed. Just like how if you push over 600 HP in a stock motor it will blow, just like you need a forged motor to make 800 rwhp and all that bullsh1t. Tuning and keeping the motor cool along with good fuel is key to keeping heads down. If youre pushing over 1k then you may start thinking other sources
6 bolt heads with distorting over sized head studs will still push water, its just how much is it going to push between passes

Regardless of what you did, they are still notorious for pushing water more easily than the other LS heads. Just because some people don't have the issues, doesn't mean everyone is that lucky. I'm sure good tuning has a lot to do with it, but they still push water more easily. Facts are facts.

They still push water more easily. That was the debate. End of discusssion... or at least my side of it.
