Hey guys, I got an 88, but I'm going to be putting a 460 in. I got lucky and got one out of a 71 Lincoln, but the heads that came on it are a 73 lincoln. Do any of you guys know how to tell if those are the police interceptor heads, and if they are worth sprucing up? I found specs on the int/ext ports, but I can't remember what they are off the top of my head. Any of you know a good website with specs. for Ford cylinder heads?
