I know this isn't a big block part but maybe one of you has a parts number book. I have one set of SS intake valves C90Z-6507-AA???? I'm going to clean all this crap out soon, I promise........LOL
what do you want to know? If you want to know what engine they are for, measure the valve head with a precision tool like a digital caliper, micrometer, etc.
My guess is you measured the valves with a tape measure and got 1 and 7/8. I still don't know what you want to know? reply back, in the meantime i will try to identify the valves. Btw it is a pain in the rear to find out about them because they books don't really list valves.
thanks...thats possible, they are still in the Ford boxes, and are marked intake, but they may have been mixed up...my specs on boss 429 exhaust say they are 1.895-1.905..
