Well my 164 blew a head gasket last night on the way to the mechanic to do the brakes (ironically enough). Bummer. That may have been my cooling problem all along. I hadn't driven it for _real_ (i.e. more than a couple miles under 40mph) since I bought it. It conked out around 15 miles from home. They're going to replace the gasket, resurface the head, and do a valve job, but is there anything else I may want to have them do while the head is off? It's a 1971 164, carbureted.

There don't seem to be a whole lot of power increase options for the B30, at least from IPD. This also isn't something I am necessarily considering but if it wouldn't be a hell of a lot more expensive for them to do, I _might_ consider it.
