I know nothing about Buicks! I howevery am lokking at few diferant cars to buy. Some off these cars are buicks. I like the 62 Buick body style allot. I know what a nail head is. The cars I've seen don't have them. My concern is leaded gas. I know I can put a addedtive in. My question is do they share heads with s/b chevys? Are thier any newer heads in the junkyard that can be swaped that like unleaded. The reson I'm asking is becuse if I find one it will start out as a daily driver.

The Nailheads have a relatively low spring pressure and the heads are decent as is. Unleaded shouldn't be a problem. I've been running my '57 364 for years without any issues, and everyone in the Yahoo Nailhead group pretty much feels the same. There are no other heads that bolt on except Nailhead heads. the 401/425 are the best but the 364 will interchange, but then you have to use a 364 intake.
