yes i ran a search...
i have a knicked valve in my b16 head, im looking for a factory exhaust valve ot replace it, a friend of mine has all his stock vlaves form his type r head, since he replaced wiht aftermarkets... can i use one of his stock exhuast valves ? are the specs the same between b16 and b18c5 ? i know most parts in the head are... please some one clarify this for me
or if nayoen has a sotkc b16 valve ill take that!

 

type R's are suppose to be a bit lighter I think. But not too many people use then since you wont see much of a difference.

 

the type r ones are thinner and lighter. my brother worked at a machine shop and i remember him saying something about how you shouldn't do valve jobs on type r valves because they're already so thin. If i remember right, they'll fit in a b16 head. you should go ahead and replace them all.

 

for some reason i was thinking that the b16 and b18c5 valves were seated differently, but im not 100%. mihgt want to double check before you rip the head apart.

 

yeah i heard all that crap too..still not sure if its true..but my friend says they fit right in..im suppose to have ITR valves in a B16 head on my B20..but the head did come off hes B18C5 soo..but im thinking its a C5 block with a B16 head...same difference..both heads are PR3 castings..!
