Ok I have a fully built h22a bottom end ( Darton MID Sleeves, JE 9:1, scat rods, polished and balanced crank u name it. I am working on the head now valve train will consite of Skunk2 components, with a nice port and polish job. I have two questions #1 is it ok to run Valves .5mm bigger on a turbo project. #2 I have Skunk2 stage1 cams can i use those cams and just get it tunned or just use my stock cams and have them tunned. Would it even make a difference, any help on this matter would be awesome thanks

 

from what i understand running oversized valves with turbo is ok. however runnig oversized valves with those cams is not ok.

 

which cams u speak of the stock ones or the skunk2 stage1. On there sight they say not to use oversize valves with stage2 or 3 vtec cams.
