Is there any other reason other than blown head gaskets that there would be bubbles in the expansion tank? Just put this car back together finnaly after 6 months because of head gaskets and dont want to do it again. Thanks.

Heads were not resurfaced but were checked and found to be straight by a machine shop. Could it just need a couple of warm up cool down cycles? Just let it idle up to operating temp for a second time was doing it at first and then stopped. Its running pretty smooth other than an occasional slight miss probably from 6 month old gas.

All the fast cars blow bubbles in the overflow tank.
