I had a set before, they should be 186's with 64cc closed chamber and 1.94/1.50 valves, they were used on 295hp 350's in SS cars. and are worth it.
Thanks for the info 74.
I'm not up on the numbers. Is 186 a casting# and if so where would I find said number? How much more do you think they are worth? I was thinking selling them, but if the're only worth a 2-300 then I won't bother.
