See the specifications page.

Can someone update the specifications pages to include this info? Perhaps I am looking in the wrong places...

the stem width is 11/32"

I had a set sent to me, but they didnt fit, now i know why.....

oooh Iron head 3.4L.. makes sence now. I was all. "L32"?? wtf 3.4L is that (thinking of 3400) I see now, Hmm never knew the Iron 3.4L engine code.

intake- 1.72 head, 11/32 stem, 4.706" long, SI part number SEV-3253

exaust- 1.425 head, 11/32 stem, 4.737 long, SI part number SEV-3188

those are what i run in my 2.8l ironhead motor. the heads are the same between them.

the SI valves you are running.. do you feel it was a nesessary upgrade over stock? are htey swirl polished? I was looking at getting a set for my car when i build the motor. they will be seein forced induction so i was looking at coating the exhaust valves to help them not melt. any suggestions?

i didnt see it nessesary, however i needed valves and wasnt going to cheap out. being you are running boost, i would deffinitly recomend them. they are swirl polished.

I also plan to turbo in a couple years, but I have a lot of modifications to do... I used 2 valves as protection when doing my CC, so I needed a new set... I though, I might as well go all out.
