I have been doing fine with FEL-9292PT head gaskets on my 4.8L LR4 Boosted 10 psi around 450HP stock heads and bottom end.

Now Im upgrading to Trick flow ported heads, 302 duration cam, and same turbo kit 10 psi boost and thinking about upgrading head gaskets and was wondering if anyone knows of better? Made crazy power with the Felpro 9292 gaskets and I'm worrying for nothing?

And yes, I have looked on Trick Flow, Summit, and Felpro to but cant find definitive answers.

thanks for the help

A lot of guys use LS9 gaskets, some say the bore is to big below a 4" bore, but others say no problem, so who knows, lol

LS9! That' a good start! Thank You! Well even if the bore size is a little big, As long as the rings seat to the surface, at worst we will lose a smidgen of compression. No biggie.

Run the correct Bore headgasket. You do not need LS9

Yep...any stock GM MLS gasket will easily hold the power, so nice to run the correct bore size.
