Terry, what exhaust gasket did you use with the hytech? Mine is leaking a little with the old one I reused the old one.

I wound up using a new stock GM one. I had purchased a copper one, but because of the way the HyTech header flange is sculpted (instead of being a simple rectangle) there would have been a fair amount of blow-by because the copper gasket's ribs would have been outside the header flange.
