Thanks jsveb I hope your car and it's killer paint job is going well.
Yeah, I think balancing helps a little, it sure can't hurt.
There was a difference of up to 3 grams between the pistons and removing some metal at the inner ends of the wrist pins is the easiest and safest way to make them all weigh the same.

Opening a new box of Mahle 3.3 pistons and cylinders...
The wrist pins came wrapped in brown paper and they were inside the white styrofoam things inside the cylinders. The pistons came inside the cylinders. A good safe place for them.

I lapped the cylinders to the heads with valve grinding compound. Not needed with new ones but it didn't hurt either and I knew they were good that way.

Cgarr machined my rocker arms. They're running on 964 cams I carefully timed to open the intake valves 1.26mm at TDC before the intake stroke.

Opening up the intake ports to 40mm to match my 40mm aluminum injector blocks.

A finished intake port. I had little pieces of rubber hose pushed on to the valve guides to protect them while doing the porting. usual I'm going off on fragmented tangents from the original post so I'll stop now.
