You are going to have to get those custom made depending on deck height and base height. Nobody is going to give you accurate or useful info

You might check with Brian @ Thrust Innovations on this. He did mine years ago, Wiseco piston and 85mm bore +8 mil crank..

Like the Buzzard said, he had ordered custom cut domes fir it and had to recut 2 times more to get the compression near where I wanted it. Believe Dasa supplied the custom domes and did the recutting

May need to be more clear on what pistons you have. Are they kawasaki pistons or are they flat tops for the specific profile for that cylinder. Not all flat tops are same angle or truly flat

Might want to tell us what head you have? Back then those cylinders used any AM Head.

I built a lot of these back in the day. Both race and early FS/FR.
to answer your question, depending on porting? Squish, and a variety of other factors.
your needing to be 26-28cc, to yield 200# cranking compression.
like JC suggested, ADA made an off the shelf dome set for these motors.
I had very good luck with them. I can help you source what your looking for.
there is even a very good chance I have something close to what you will need in my
used parts stash from back then. Please email me direct, Paul@lehrperformance.com
if I can be of help?

When the need arises, I’ll be using your service, I’ve seen your porting work, very clean porting!
