273 Commando Slugs

I used a CD Blank from my computer, put a thin coat of vaseline around the outer ring, pressed it to the head, then a syring with oil in it to CC the heads on my 440.

I plan todo the same for my 273 as I get into the build of it.

I found the #6 had spun a rod bearing. Looking at re-conditioning, and seeing IF the slight grooves in #5 and #6 holes can be honed out without having to bore it. Else, I'll be looking for some of these pistons at .010 over as well. Already looking at turning the rod bearings on the crank because of the grooves in it on #6.

If the pistons only come at .030 over, I guess that will have todo.
