i know they will bolt up and work but what kind of power/tq am i going to be looking at? my ls1 now with these heads make 370rwhp. these heads will be swapped out at a later date for some 243s or better but have to make these work for now. will i just lose power up top or all over? guess i will avoid the dragstrip and just try to enjoy the car this season and do the upgrades next winter. thanks
