A-Bodies...Big Motors / New Hemi Duster - FINAL ASSEMBLY

I know room is at a premium but these heads are supposed to be exact demensions and look of stock heads. I am thinking about going with them because I need to replace a couple of valves and well I just can't do that so I would replace all and by the time I do that I would be close to cost of a new set of Heads that could give me more power, less wt., and better cooling. This whole build has me completly confused I just can't make my mind up on stuff. I did find an mp dual quad intake and carbs so that is what I will run for intake.
