Wow, yeah im pretty much sold on keeping my iron heads. I have a boost controller already and will be installing a "rock-on" level 4 with a 3000 fuddle stall with the 6.0 so i guess the best thing to put the money towards would be a gt67.

i said to keep the iron heads because they would retain the most heat as it would take more heat to soak them so more heat would pass through the exhaust. Al. heads do have their advantage like you mentioned but not enough to justify.

Unless there is a good amount of power difference between them, like at least 15hp then i think i'll stick with the iron heads for now.
