[mikeyrocks]

ok i have a 93 cvic hb.. it is nice but it doesnt seem like anylose of power but it smokes alot when i give it the gas or down shift and get on it....i am wondering if it could be the valves...or rings.. i took off header and noticed allot of resign and gunk all crammed up on the valves so i am hopping it is the head because i am doing a mini swap this weekend but i wont if it is the spings..so anyone no what it is or more common head or block...the head i no has carbon caked on everything and lots of smoke but you tell me email me if you can or want [email protected] also and selling stock sets from it and few other things thanks, mike
