What Valve Springs are these? (Help Identify)
What Valve Springs are these? (Help Identify)
I bought some heads, they have these dual gold springs on them, they look to be either Patriot Performance Gold or PRC springs. They are made by the same company I know but how am I to distinguish the two sets? Is there something in them that have a diff color? Im going to pull a spring and snap some pics, maybe I can find a local performance parts store who can match em. Any help is appreciated.
I found this info:
Here are pics of mine:
Here are manufacturer pics:
Patriot Gold
PRC
Patriot Extreme Dual Springs (silver inner spring/mine are gold)
So I see there is a diff in the locks, what will be the diff in the 10 degree versus stock valve locks?
Thanks
Mike
