i've been reading how people on here are building all motor ls motors with high compression blocks. i jus blew my stock block and i wanna swap in my high compression one now in its place. the main thing i wanna be sure bout is can i use my stock ls head on the high compression block? im goin ls/vtec in about a month or two but im jus tryin to get my car runnin now!!

 

the thing is you need to have it tuned on this said high compression block on the ls head then retuned on the vtec head. that way you dont damage you pistons if you lean out from no tune.
