I put a shortblock in this thing bout 8 years ago. Figured it was time to decarbon the chamber. Course I had to modify stuff while I was in there. When I carried all my K321 stuff to the machine shop I had taken an extra head. Had .040 taken off both the extra head and the K321 head. The extra head now resides on the K301. Seems to be much smoother and the throttle response is improved. I also found the muffler was toast. So I put the 1450's muffler on. The 1450 is gonna get a custom built muffler anyhow.
K301 old head on top. Head with #2 is now on the K301. Head on right is going on the K321.
Block top after cleaning.
Piston top, lot's more life in this engine
The mufflers
And a little score this weekend. A stripped 44" deck to replace my rust bucket
