nah, just the ones I have in there. Schneider HD springs. 100lbs seat pressure.
And I looked into my coolant pushing problem today and I think I found the problem.
Here's left to right under the intake manifold:
the head gasket looks delaminated right there, and I'm pretty sure it has to be coming from there since there was coolant all over the lower part of the intake manifold and everywhere on the engine crossmember, motor mount, frame rail, etc.
So, I asked around and my best bet for holding big power is to take the block out, completely strip it down and get it o-ringed.
