Ok yeah I think I smell what you're steppin in now, sorry to be so stubborn about it.
The replaceability of a head gasket is what keeps me coming back, as well as a little forgiveness for a possibly less-than-perfect head mating surface. That soft aluminum is hard to keep *perfect* during a top-end service. Getting a bad head gasket or poor installation are definite pitfalls tho, I hear you on that.
Generally speaking though, lower compression is kind of a different goal than most. But if you're deleting a decomp or looking for reliability on a kitted bike, I can see the reasoning.
And the port timing... I guess if you're messing around with them anyway it's not a big deal, but something about raising the intake makes me dislike the whole concept. Probably a dumb hangup
