The part number you are looking for is the 2033. These are the 2.05"/1.57"/59cc lS6 style heads. We begin with new GM raw 035 castings. These and 243 heads have the same intake and exhaust runners. The only difference is the combustion chamber size. Because the raw GM castings are +.050" on the surfaces, we are able to preheat these heads, weld the combustion to a very small size, and send the heads out for heat treating. When the heads come back we do all the maching and CNC whatever chamber size we want in the head. This is how we can provide a 59cc head that is factory deck height.
Bare in mind that when you dealing with PTV clearance you are not only worried about the deck height of the head, but also the valve head diameter. A cam that may clear on a 2.02" valve, will have less PTV clearance on a head equipped with a 2.05" valve. ALWAYS CHECK PTV CLEARANCE !!
These heads with the Ferrea valves will be $1,295.00.
