sunk valves, stem height problem

Chebbie undeniebly had a winner with its SB. Biggest thing over SBM is the angle of the valves in relation to the combustion chamber. I had a SBC running alkie with a blower injected making 1280 HP. Was in our mini rod tractor for tractors pulling contests. Mopar made some good SB heads as well. And not all SBC made a lot of HP.
