sounds good, put it back together with new rings and bearings, have the heads fixed up a bit and go have fun.

The can in the lifter valley can be removed, if the there is a plug (metal frost plug) at the back of the block where the old draft tube was placed. You must the use a 350 style pcv valve (try a 1968 327 pcv valve from your auto supplier) in one valve cover and a vent in the other. Like the old 350's had.

There was an old GM conversion kit which is not available any more.
See below.

This was used with a push on breather cap on the filler tube at the front of the intake.

I hope this helps you
