Ok, P4529442/P4529443

they are said to be 112.2 mm long

well... http://www.thedodgegarage.com/turbo_s60.html
here it states that the big valve head uses these. this is a g head of course and g heads need 114.2 mm long valves.

how does this work? i don't understand....why can't i get the 44mm intake and 36.8mm exhaust for the g? i know they are somewhere because my friends Steve M head has em...do the over sized seats make the difference?



while i'm at it, why do i need a special head gasket for an o-ringed block? (P4452008)
my block is ringed and i've been running a 2k6 gasket at 23 psi with no issues....

I'm pretty sure you've got the heads and valve lengths reversed. Bathtub head gets the shorter valves.

Steve M doesn't use MP valves in his heads.

MP no longer makes the G-head valves anymore. You might be able to locate old stock but thats it. FM and FWD sell them though in nice stainless, :thumb:

I can get you big valves for the G. I have them custom made and the turn around time is usually 3 weeks. They will require larger valve seats.
