type 4 valves
 

Hi guys,

I am curious to see some offers of type-4 valves.Don't know if I should go for stock rebuild 41*34, or get bigger valves, but I did not foud yet 42*36 or 37 valves and seats.I would not go bigger.
So who sales type4 valves? thanx!

I am also in question with Martice. Who out there makes the valves and seats for the Type IV? Manley? TRW? Others? What material are they made from? Stainless only? What about seat material?

What I know is that CSP sales Manley valves but from 44*38 up...
Also some OEM quality valves but also very big...and no seats for neither of them.CSP has all stock valves at good prices, but the 42*36.
Pelican parts, has porsche 42*36 valves but they are about $50 each! Much more than the csp Manley valves...
So where to buy from? :)

Maybe you could try Riechert Tuning. I think they're in Germany? How about trying a post on the POWERTUNINGPARTS forum. They're also in Germany. We'll keep this up until answers are found,huh?

Greetings. Here is a website to check out. www.sivalves.com/ I did not see a listing for the seats, but contact with them should set us up.
