340 X head advice

Sell them to a numbers guy and put some aluminum heads on it.

I have thought about that

If you NEED to have a numbers matching engine.....
Then use them. The max you should be bothered with is a bowl porting with good 2.02-1.60 valves and a gasket match which the gasket matching is adding very little.

I thought about what RustyRatRod said and going with aluminum heads and it's not a numbers matching deal. My plan was to pull my 273 Commando then make the 340 look just like it with the valve covers and air cleaner. A sleeper deal so I kinda wanted to keep iron heads.
