Heads, how much gain?

well, would i be better off paying someone to port my 452 heads, or buy aluminum aftermarkets and run them with the stock ports and all, just have them checked?

Aluminum. Ported or not apples to apples you'll have less money in them than the iron heads and less weight. You'll also have a repairable head. In OOTB form you can see they outflow a stock head. I run mine OOTB and they are fine, pass leak down and go 11.70's.

I also need help i getting this thing to hook up. Its actually fairly quick as is but doesnt hook up. I want to do the inboard rear spring relocation kit and mini tubs so i can put some tire under it but i dont have a welder and cant weld anyway. I dont know anyone around here i could trust to pay to do it right..Thats the problem with owning a dart, not being able to get much tire back there..

Doesn't hook up on the street or at the strip? The strip is VERY different. Much stickier!

You don't need a mini tub to hook up at the strip. On the street the mini tub is going to help you hook up better and looks tough too.

You can fit a 26x10.50 under your car with nothing more than offset shackles. They have cars in the 6's on 10.50 rubber trapping speeds over 250mph.

The only thing that has to be welded for offset shackles is the new perches. Nearly anyone could do that for you.
