Hey guys, Got an EFI head I'm about to get reco'd, but the guy is pretty reasonably priced so I'm looking at porting and valve work at the same time. I'm looking to maintain 100% streetability as it's my daily and it's not on gas - so it's gotta maintain, or improve on, current economy figures. As far as valves go - what should I look at in terms of size, and should I look at both intake and exhaust, or just the intake side? Porting is an area I'd like to try my hand at - but given I want a mild port (something just a bit better than a basic casting cleanup job), is this best left to the professionals too? Engine's getting EFI gear, and is on a stock bottom-end, with a reco and recurved dizzy and soon will be looking at a custom-grind cam too (again something sensible). I'm hoping for, all up, around 120rwkw out of it at the end of the day, before I go playing with the bottom end and ECU, if ever. So keeping all this in mind what're your recommendations? Cheers, Chris.
