Not that it’s a big contributor, but the cover, and if possibly the block should be lapped on a surfacing plate/table. Using Scotch Brite rounds the edges of metal, reducing the flat mating surfaces andi introducing irregularities.
The same surfacing plate can tell if the cover and/or the block are warped.
I have 3 FD powerheads in the basement that were victims of leaky exhaust covers… so insidious when the water leaks internally and isn’t seen. I thought I had # 4 when I started it 3 weeks ago and there was so much water under the cowl that I thought the exhause cover had exploded.
Turns out the welch plug on the bottom of the head had let go. All the water coming up from the impeller left the motor via the resulting hole.
