Hi it seems that I'm a little late to tell you that the 1.94/1.60 SBC valve swap but I will tell you that I just wrapped up my swap and it was a job trying to find pushrods to fit it, an a expected but feared problem. The pushrod dilema was easily solved by our good friends from Summit, $136 & 2 days later I was ready to rock and roll. When I fired her up Man! She runs great with a Comp Cams 280 K-kit.
