Quote: I'd just go with the KB 400's and 84cc Eddy heads. I think on a budget build the extra compression is gonna do more for you than quench and you can save from having to cut up your heads.
I agree, that's what I'm running with an 80cc head. 9.9:1 compression ratio with no detonation and no quench really (.063). Let's say it's enough to through you back in the seat and leave 50 foot slabs down the road.
