I was swapping my dual springs onto my new heads today when I realized I have a problem:
The new heads (came with Comp 918s) have the seals that are incorporated into the valve seat. These are too large in diameter to fit inside my dual springs. What is a part number or location for the proper seals? Preferably a part name or number so I can order it from a place that will get it to me in a day. Or a GM number. The seals that are separate from the seats work, for sure.

 

Oh, the springs are PRC duals. And no, I don't want to order them from TSP just because I need them ASAP and they've twice promised me to get an order out same day on the phone, and failed to do so.

 

Intake - 12533586
Exhaust - 12457652

GM #s

 

Those will be the ones without the seat built in?

 

yes but get 2 packages of exhaust seals...better seals.

 

We also have the seals in stock if you need them.

 

my dual kit from patriot came with new spring seats and valve stem seals... i just removed GMs

 

I agree with V6 Bird, for the few pennies more get two sets of exhaust

 

I think this is how the Partriot kit comes...two sets of exhaust seals.
