Howdy all, been a minute since I posted last! I am in the process of fabricating my own headers for the Crosillac, and I noticed upon pulling off the passenger side exhaust manifold that I have a bit of coolant seeping from the forward bolt hole of cylinder #5. Is this something to be severely concerned with? Also have a bit seeping from around a couple of freeze plugs, even though we used Indian Head shellac when installing them, but I have some of the cooling system sealing tablets that GM throws in every brand new car on the assembly line so I think a couple of those should seal those leaks up within a few heat cycles. Anywho, here she sits at the moment. Photo attached.
