What kind of gaskets are you using between the RA exhaust manifolds and heads?

Good questions. If it's not the windage tray or the oil pan, it COULD be an exhaust tick. That would be something that the builder would not have seen. I built a new motor for my Silvy, and during the first test drive the pass side manifold bolts were a tad loose. I stopped at a red light and I'm hearing this tic tic sput sput tic tic noise. Tightened the manifolds and it went away.

I'd check the manifolds for cracks, check the head mating surfaces and reseal with new gaskets.
