When you get ready to start w/it, why not start a thread on the engine and what you specifically want to do w/it. That way, everyone will see it and you'll get a good response.

And good idea to pass on the Thumper. There are better performing cams available, IMO.
Yes you are right about the thumper cams. There are better out there. The heads i have are some nice iron centerbolt heads with 64cc chambers. The valves are 1.94-1.5

Do you think it would be a bad idea to run 11:1 on these heads. Im going to get them milled very soon here so my chambers will be in the 58cc area. Also i do have high octane available at the pump right near me.
