Aspeed, are aluminum heads on iron blocks hard on gaskets in general..?
I see nice heads for about the same price that they were when aluminum after market heads first showed up years ago.
I know that the original Top Fuelers had lots of problems with the aluminum heads growing and causing nasty fires.
It took them awhile to figure out a cure..high temp silicone.
That's pretty impressive that your vette racked up so many miles. That says a lot about the fuel injection system doing it's job not just to deliver good power and economy, but also to safe guard the engine's health with built in fail safe modes. They are complex and full of expensive sensors, but after forcing myself to learn how the one in my Jeep works and how to identify what all the gizmos are called and what they do, I'll do whatever it takes to keep it running. I'd still like to have a simple carb, manifold and point style distributor just in case we get attacked by Martians.
