header gaskets
- most people can't get copper gaskets to seal good
- percys soft-aluminum seal very well, but people have blown them out in the past
- provided gaskets typically work well (believe it or not) but a handful have blow-out problems
- fel-pro 1470s have a good reputation here on the boards
- triple-steel GM gaskets seem to be the best buy, though. it tends to be a rarity when they don't work.
