Might check with this guy for some very nice heads, He spent a couple years and Mega bucks building a UMP modified took it out the first night and got to run a few laps,spun a bearing and popped a rod. He decided that was the end of his racing career.Plus he got laid off last month so he might be willing to deal. Might be worth checking into. He lives in St.Peters,Mo.
