Gotta love small blocks!

I ran my Duster with a 318 I bought for a few hundred bucks after I found the original /6 was toast, before I swapped in the 340 it has now.

Yeah but sunflower seeds are easy, they don’t belong. Busted valve locks came from somewhere.

Doesn’t look like valve locks. It looks like the bottom of the retainer broke maybe. Stupid mistake, the piston, but it only looks like 1 cylinder.
Check the cam lobes on that hole.
