92948, Anyone using SI Valves Portflow Series stainless steel valves?
Posted by dougie2, Sep-09-05 03:35 PM
I just picked some up for an un-beleivable price (the guy didn't know what they were). I'm 95% sure these are the same valves that Exile Racing carries.

Anyone using them? How do you like? Have they held up?

I got my SS valves from Exile, well actually this is my 2nd set from them. They were beautifully made!! I was very impressed with them. They were designed much much nicer than the stock ones. Wish I would have taken pictures. It's one of those things though that you don't really "notice" a difference with. Mine were standard size, and with the rest of the head components my revs are wonderful. It's hard to explain.

If they are the same (I never can remember the brand for some reason), they are fine. Perhaps the coolest thing about my car is the head from ERT/Fierro. :thumbsup

I have the +1mm size w/ a 5 angle. No complaints.

I can vouch for that, they don't damage the piston. I would rather shell out another $200 for new valves than all that cash for new pistons. (my timing jumped 2 teeth, with a milled head, that's all that is needed)
