It's a kind offer Howie, but I'm..... picky 

Quote from: ducpainter on Yesterday at 06:55:02 PMI'll never forget the time, when working in an auto body shop, I was running my hand over a panel, and smashing it with a 3 pound hammer. I'd run my hand back and forth, and give it another whack.

Of course I got out of sync, and smashed my hand. The owner was standing behind me watching and his hysterical laughter was almost enough to ease the pain.

Blokes tend to offer that kinda sympathy, eh..... 

Or just send it to be recycled.

I'm going to stand fast that you need to pull that head.

As mentioned 1;
belts - if it jumped a tooth or two a valve could suddenly be where it shouldn't

As mentioned 2;
a bent valve (seized?) might also suddenly be where it shouldn't

Which leads back to "As mentioned 3" - heads off and pray , and please remember to take pictures and to share them.

Quote from: dimirex on Yesterday at 11:00:05 AMWere the pistons a direct drop-in or did you have to use a thicker base gasket (or machine the piston) to achieve the optimal compression ratio?

I have gone through a few piston kits. My current pair required a different solution for ideal height/squish edge, than the previous pair. Sorry, can't remember if that is with or without the thick (~2mm?) base aluminum gasket.

Fortunately, I only needed to replace the plug on the vertical cylinder, which was the only one showing impact damage. What internal issues would cause contact with the spark plug?
