Machining Domes For Stroker?

What does anyone do for this? Do you start with a blank dome or just modify an existing dome. I will be needing domes for a 4mm stroker and I was thinking of modifying 42cc domes. If I machined 2mm off the squish band from a 42cc dome it would make it approx 37cc.

The squish band will get very wide when you cut the squish for strokers and then you need to machine the bowl in the chamber to correct the squish ratio percentage, also remember the compression ratio goes way up when you poke the piston up into the dome. Not enough info as to what your trying to do to give any more info...(bore size, pump fuel, race gas, what ignition, how much timing, what pipe and porting spec's etc.etc.)

If I ever get this thing together I will get you to make me some domes.

I was going to get Art to to do everything for me but I changed my mind. After a bit of advice from Supertune I decided to go with big bore sleeves made my Northwest sleeve. They have a lot lower transfer ports. From what I have read the transfer ports on the stock cylinders are too high for good smooth low end power with a stroker crank.

I still could get my domes from Art.
