hi,
im in the middle of rebuilding a friends cvh cylinder head, after his cam belt snapped. i have changed the valves, and lapped them in, and have put it all back together, lifters, rocker arms etc. But, this is the question, when i put the cam to the timing mark, number 2 exhaust valve is open by about 3mm. is this normall on a cvh head, or could there be other problems, like the cam for instance??
cheers harry

 

sounds normal to me, 1 3 4 2, 2 is on exhaust stroke (ex valve open)

 

yh sounds rite to me m8, as long at timin marks are sopt on it should be fine

 

Yup thats fine mate.First time i did it i thought the same.best of luck with the rest of it.

 

As said don't worry about the valves in anu cylinder other than the one you're doing, ie no1.
BTW, if the valves have been cut on a serdi seat cutter no need to lap in, they seriously are that accurate with seat cutting.
