aluminum heads for my 67 330 engine?
Was thinking of replacing heads with a lighter option....have the 330 high compression. Have a valve going bad and may pull the heads....Your opinion please..Would these provide as much performance or better? Than my 330 heads?......Thanks....http://www.ebay.com/itm/Oldsmobile-A...1ZVtoe&vxp=mtr

Those are BBO heads. To use them on an SBO like your 330, you need to mill them quite a bit to reduce the size of the chambers. You need to replace your mechanical fuel pump with an electric one because they won't clear the pump. You need to use a Performer RPM and have it port matched to the larger BBO ports. There is a LOT of "collateral damage". As noted, have your original heads redone.
Am I falling into the Aluminum head hype? Or are they ( Aluminum heads ) an advantage ( besides the weight ) I hear that they take longer to warm up in the winter ( almost here ) But do they produce anymore horsepower for the the swap?......Weight loss vs hp performance?

You need a pair with the 64cc chamber like above. Avoid Mondello Performance, if at all possible.

Quite frequently now when i start the car ( after a little cruise ) I get a backfire and black smoke puffs out of one exhaust.....Valve spring job? vs heads redone?

You want new 2"/1.625" valves with the bowls opened with a cutter, milled for straightness, multi angle valve job, new springs, guides and seals. You can upgrade to positive seals at this time. That is what you want done.
