What goes here?
I just picked up this motor and I don't know what this hole is for. It's right above the spark plugs, one on each housing. Theres cracks around it and I don't know if I should worry about them. They don't go into the threads and stick out so I don't know for sure if there actual cracks or not. Thanks for the help.

The only thing to worry about concerning using two front or rear housings is the bypass air hole drilled in the exhaust pasage. It is the only reason there is an
"F" and "R" stamped on the housings. Everything else is the same. The rear has the hole to the front and the front has it to the rear so they can each pick up exhaust gases coming through the center plate.
Of course, if you have blocked off everything and aren't using emmisions, then it doesn't matter.
