Bob Spanaway is right. If your going to use the crab dist use the 59 gears, thay with thrust back against the block,(the 8BA gears thrust out and rides on the front cover and is't apped to push against the crab dist) As far as plugging the 2 water holes ( one on top one on the front) a 1/8 pipe tap will put a thread in the hole and us a 1/8 pipe plug with an allen head. Put a little JB weld on top of the plug and you won't even see it. PCV valve works best, just use the 59 breather pipe under the front of the intake manifold, It's easier to use an electric fuel pump and just use a stand pipe on the rear to put oil in and a tight cover with a grommet on top for a PCV valve. Don't worry about another hole to suck air in, It will suck enough air around the dip stick and what ever goes down past the pistons and rings. I would just put a short 7/16 bolt down the fuel pump push rod hole because the 8BA rod bushing has a little pee hole half way down the hole that goes into the main oil line. The hole is so small you wouldn't loose any oil pressure if you left it open but it will spray a little misst of oil up into the valve spring area, a little more that the intake guides need. People have been running 59 heads on 8BA blocks for years. Walt
