Ok well this is what I came up with. I called Elderbrock to see what they had to help me as far as heads, and cam. After about 20 minutes of explaining why I was using such a small ci motor we came to the conclusion that they didn't have anything that would work. He even said that he didn't think any(manufacturer)of the new aluminum heads would work. Said something about the valves hitting. So, what I'm going to do is use a set of 58cc PowerPack heads that I have. Im going to get them cleaned, resurfaced and valve job. I figure with the heads and a .021 head gasket I can get the compression up to 9.91:1. By doing this I also save myself a few hundred by not having to buy heads. I really didn't want to buy heads and have them cut to work. Just feel like it was wasting money....especially on a small motor like this. May not be the most powerful motor but it should carry the 23 down the road pretty good.
