the ones i'm gona us on my head are ferrera competition plus 1mm bigger intake & exhaust and the same length as the trucks, but they are 8mm stems instead of the 7.35mm stem of the trucks (at least i think that was the dia of the truck valve stems, you'd have to check ae/clevite for exacts) but you would have to get new valve guides made, paeco ind. is going to make some for me along with some performance valve springs & retainers, they will use the stock valve locks.
ferrera p/n's
f1834p for the exhaust (37mm head dia, 111.68mm long, 8mm stems)
f1832p for the intake (45mm head dia, 111.9mm long, 8mm stems)
so the trucks specs should be
exhaust valve (36mm head dia, 111mm long, 7.35mm stem)
intake valve (44mm head dia, 111mm long, 7.35mm stem)
like i said above for exacts check ae/clevite's catalog cause i could be a little off...
