Compression ratio what to do??

Keith Black 243 will sit proud out of the deck, but they are hypers.
It gives me 8.98 static, and 8.06 dynamic using the same cam.
It also has uncut X heads, the chambers are huge on those heads, mine were 77cc's. but I chose them because I am tired of buying high test with race gas to cruise around in, and I also used the thick felpro gaskets.

I want a cruiser out of this car, that might be easy on fuel.
