I'm building up my 01 b18b. it has 70k on the engine. I do not want to go Vtec. I am planning on putting in jdm p30 pistons, crower valve train and crower 403 cams. Someone suggested That for a street driven car the best thing i could do would be to get a good valve job and mill the head. My question is how much do each of these cost? And where can i get it done? Also what is the difference between milling, porting, and honing? does one offer more than the other?
