ok...i think the wise decision is going to be to rebuild the motor. make it new again. it burns some oil under hard acceleration now and prolly could use some bearings and rings. whats a good source of parts?? is it better to buy an aftermarket head or just get a good port and valve job? how about cams...who offers the best performance cams? is there any kind of rotating assembly kit that would have all rods, pistons, crank, etc...?? any suggestions/tips/advice?
