Rebuild 915 heads or go aluminum?

Lemme ask this would you go iron for just under a grand or aluminum for $1200 or more...? all things being the same in CFM and just saving the weight?

Personally my whole issue with "go Speedmaster" is if I order them I want to bolt them on and skip the machine shop (which is where Im spending the money with iron)

if I need to send new Speedmaster to the machine shop I dont see it as more than shaving weight for 500 more after the machine shop.

I have a set of SBM 915 Js in the shop right now with the works being done to them(no porting) for $950 out the door just for the backstory.

The one thing that I think is great about the interwebs is there are plenty of people who will tell you how to spend your money :thumbsup:
