6-bolt Head comparison those with good & bad experience please share
Shopping for 6 bolt heads for a 388-430" engine build, probably stepping up to 76mm twins. There's a huge price difference in assembled heads from as low as $2500 255 TFS with tia retainers from Tooley to $8000+ for some of the big hitters. TFS, PRC, Chevy Performance are all closer to my budget unless someone convinces me spending more will get me greater durability (highest importance) or huge performance gains(which is NOT real important to me on this). Block prep, assembly and tuning go along way toward good head gasket sealing. The engine currently in my car is a Stock unfilled LQ4 block, stock crank, shelf wiseco flat tops, LS9 gaskets and ARP 11mm studs and has NOT pushed water in the 3 years it's been together making between 1050-1200 flywheel hp. 10.5-11 to 1 on E85. I really feel statements like Mast's decks and castings are stronger than TFS doesn't really matter at the 1600 flywheel hp I'm shooting for. I'm open to either LS3 or LS7 style ports.
