Changed intake gasket, now it won't start

Everything I read says not to use the front and back cork gaskets. I guess they end up leaking. (Hahahaha, would have been better if I used the first)

Some combinations of heads and intakes work fine with the original end gaskets in place. I would temporarily place the intake on the heads and the intake gaskets and snug down just the corner bolts a tiny bit to see how big the gap is. If it is large and close to the size of the cork gasket thickness, then I would use the cork gaskets and a skim coat of black RTV as a sealer and glue, with blobs in the corners. We have a 340 that uses the cork gaskets just fine. So it depends on the particular combo.

I cut the end tabs off with a razor just to keep them from getting in the way and causing leaks. They are just an assembly aid that likes to get in the way!

So just how creamy is the oil? I would be changing that out pronto; it certainly has coolant in it.
