When I built my 59 engine I used the Chevy valves (1.6 int., 1.5 exh.) because I wanted to install new inserts anyway and the longer stems worked OK with the cam and adjustable lifters I used. The Chevy valves were readily available, are advertised to give better flow around the upper stem area, and were less expensive than the NOS Ford valves that I priced. If i had gone with the logic that 1.6" valve are no improvement over 1.5, them maybe I should have just left the bore stock, forgot the lighter Ross pistons, the L-100 cam, the stroker crank and all the other little things that were done with the hope of getting an overall better performing engine.

thank for the info, JM 35 Sedan. could you please provide part numbers for the valves, brand name and a source? i am building an engine w/L-100 cam that is very similar to yours. any info you could provide would be greatly appreciated. thanks again...jack orchard
