ok, im looking to increase my valve size, i need to know the valve diam. and the overall valve length on a series 1 motor. i need the info on both the intake and exhaust valves.
im picking up a set of heads and vavle covers next sat. but i just want to see if maybe i can use race valve in these heads. im loking at undercut mildon race valves for a sbc. i know the stem diam. is the same. and might go to 1.5-1.6 exhaust valves and 1.94 intakes if they will work with the overall valve length
can anyone help me here
