    I traded a guy for stuff for some FI heads a while back and tossed them on the shelf in anticipation of an upcoming TBI swap. Well, I just pulled them out today and ran the numbers and they turn out to be 305 heads, not 350's like I was told.

    It's my own fault for not checking in to this sooner, but now I'm trying to find info on these heads so I can see if I can still use them. The casting number is 14102187. I know they are 58cc chambers and 1.84 x 1.50 valves, but that's about it. I know some of the circle track guys run the 58cc heads on 350's for the compression ratio boost, but I'm wondering if the intake runners are still 170'ish cc's or are they smaller than a 350 head. The motor I'm doing is a basically stock 350, but I'm adding TBI, and I wanted to use FI heads since I already have intake, etc and didn't want to mess with the intake holes. Any ideas?
