273 commando progress

Tadams,
What did you do to the heads, any milling or porting? What head gaskets? What compression were you aimiing at?
Did you keep the intake manifold heat riser open?
What carb and choke will you use?
I have decided to keep the 273 commando very close to stock. I am keeping the carter afb 4 barrel and the stock cam. I replaced the heads with a used set adding new valves. The gasket set was from felpro. The head gaskets were very thin metal. I did some cleaning on the exhaust but not a lot more than that.
Pistons were replaced with an original set of dome pistons and new rings and bearings throughout. As far as compression I haven't given it much thought. It was 10.5 to 1 factory but I'm not going to guess what it is now
