you don't have to swap out ECMs, just drill the intake for a dist, and run the stock TPI electronics.

How much do alum sbc heads usually go for?

Depends on which ones you get. Average price for a street head is probably between $500 and $600 a head.

By the way, I'd rather run the opti and the LT1 electronics so you get the sequential injection. Better power and fuel economy.

Good aluminum heads are over 2 grand new.

I am not so sure about the better power because it might be that we have sucky intakes but change that and I would think the L98 or LT1 is capable of the same power.

Dart and Edelbrock make pretty decent street heads for under $2k. Now if you want to go ***** to the wall and get a set of 18 degree Brodix heads, expect to pay $2k+ easily and probably another $2k for the valve train and intake.
