alright fellas im bout to tear down my all alum ls motor and id really like to do all thats possible now to seal off the combustion chambers as tight as possible, i plan on some majorrrr boost with this motor and its only got 4 headbolts per chamber sealing it along with factory mls gaskets. studding is necessary of course, already have those, but you guys think having receiver grooves put in the heads and oringing the block will help much? when i say big boost, id really like to be runnin in the 30+ range, fully plan on building the shortblock to handle it.
the issue im trying to overcome is ive read countless threads on ls1 sites stating guys are pushing coolant at 20lbs on these engines with stocker heads. sure i could buy a set of aftermarket heads for it, but its a truely pointless expense when the stocker heads flow nuff to hit the power level im after, so i'd like to stay stock there, plus they're only 200bucks each used. heads are getting ferrea super alloys of course.
i still have my cast blocked basically stock motor i finished up last spring, ill keep it for a spare, its jus too tempting to lose another 60lbs and have a longblock that weighs in at 325lbs ya know be fun to build a 900hp/ftlb sbc that weighs 420lbs built with the turb kit and all on it it'll put my boat weight in race form to around 1100ish
so what yall think? oring and receiver groove the alum block and still use the mls, or go to titan ics coppers with the combustion seals? had good luck with em in the big turb motor.
