vtec intake valves (33mm) on a ls head (31mm) possible. has anyone ever done this? is it even possible? are the valves the same length? Would the valve seats need to be replaced?

 

wont work.......

valve seats are smaller on the LS head and the valve length allong with the valve stem diameter is diffrent.

plus........i dont think the LS head would benifit from 33mm intake valves.....

trying looking for some .5mm oversized valves for the LS head......
