I blew a spark plug out on cyl#1. I got a new head (revised), so i figured while the engine is out now is the time to add some cams and other things.. the guy im bringing it to wants to install inverted pistons, crank, new rods, bearings, side bolts, main bolts, and head bolts.. is this nessasary? i thought the internals were good for 1000 horepower?? the tech said that they are not........ i also have another question, is it ok to run the car with a brand new head on one side and not the other?? please if you have the information i would greatly appreciate it b/c i only have enough money to do this once.. lol :dw:
