Hey everyone. I am experiencing my overflow tank coolant level raising ever time I run over 20 or so psi. It rises maybe a half inch or so every wot pass. No loss of oil. Less than 20 psi and it stays level. It does suck the coolant back in after driving it after a while. The head gaskets are I believe gm factory replacement graphites. It's held up well for almost 15 years of abuse and I do plan on replacing them this winter after the Buick vs Ford shootout. My question is, if I retorque them and add gm sealant tablets will this help them survive one last race? Or am I just wasting my time? Thanks

You will never know the answer to your question unless you re-torque?
It has work for us many times, and not worked a few times.

Pull the engine and re-gasket with studs. If the stock gaskets have compression going over them they will have trails burned in the surface. I wouldn't wait to fix this issue.
