Here's a shot of the valvetrain I snapped in '06 at Road America. We spoke with the owner and he said Ireland built the engine...the might share info about the head / distributor housing. Nice to see so many '02 racers there this year. There was ONE '02 racecar there in '06. Wish I could've made it last weekend.
