Hopefully the epoxy already there will stop any leaks. As for a trade, I realized halfway through the making of this thread that you have BB covers and I was looking at SB ones. I did see a set of BB covers with fins all the way across like yours on Ebay. But I don't think they were ever made that way (the M/T style at least) for small blocks, so I am still looking at maybe having the fins and M/T lettering machined off mine to make them smooth, kinda like viper valve covers.

I think yours came out great, will post some pics of mine someday when I manage to get them out of storage and start working on them.
