ive got to rebuild my engine soon deal to leaky water and oil seals. my compression is good, but im gonna go ahead and change the apex seals. what i really want to know is about porting. ive searched and looked up several ideas, but i want to use an active topic to find what would be best for me. my idea now is to get porting templates from RB and use them, but if someone has a better idea, let me know. by the way, ive got a 89 GTU w/ blitz intake, RB headers, custom 3" exaust. so what do u gurus think i should do?
