hey, has anyone done this or is it possible to put the B18C valves in a LS head???
i know the valve stem is the same size 6.5mm... but over all length i'm not quite sure on.. i know the GSR valves are 33mm (intake) and 29mm(exhaust) and the LS valves are 31mm(intake) and 28mm(exhaust). i have an extra LS head and wanted to see what i could do with it.

thanks in advance.
