aluminum heads

Absolutely depends on the situation,I got a set done for $600 complete with valves,springs etc. and quality machine work.I then ported them myself and the flow peaked at 258 and 197 @.550 with 252 and 190 @.500,waaaayyy better than a basic edelbrock head can do with out some decent money put into porting-not too mention they need fluffin and buffin otb just to be right,you can aproach $2k quick to get those results.Basicly I would kick your *** with what you consider junk iron heads lol.

LOL, well, I agree with you to a point and mostly I'll wave the flag for the iron head. Often, even with the cost of porting, they can be a better deal (cost wise) than a Edelbrock head. Cost aside, the Edelbrock with the same work would be a great head for alot of levels of performance. Then the work (Again, Cost aside) would make it an apple to apple like compare.
Also, alot has do with how you use the head. Flow numbers (Bigger) aint everything. ;)

Just wondering, had you paid for the porting work you did, what would the cost be in your neck of the woods.
(Also, please describe exactly what you did, Thanks :-D )
