What is the best head for a small block.

Nope. Those are LAX heads drilled for stud mounted rocker arms, with the stud girdle mounted to the head bolts and rocker shaft pedestals. Single 4-bbl, 423ci/360 on pump gas that made 474 lb-ft @ 3,000 rpm, 574 lb-ft @ 5,100 rpm, 595 hp @ 5,600 rpm and 629 hp @ 6,400 rpm where we shut it off. Toaster IQ52 and his son's magic. Are we having fun yet Rosey?


I always have fun. I just never get the love for stud mounted rockers. I know some guys (especially the Chevy guys who think GM made everything as God would have and think GM engineers **** gold and wipe their *** with 100 dollar bills) think they have some benefits, but I don't see them.
