Larry, Its not a very pretty piston is it,I don't know why I was thinking it was going to be a forged piston.
Is the one on the left a forged piston or did you give it a massage?

So its a 9:1 piston with what CC head?

I'm not to sure about welding up the dish, for some reason the just doesn't sound good.

Can you deck the block and head to bring it up a little bit more?
