86 Black Roller 318, swap/interchange into 72 318

Plan is to re gasket Blue 72, to my knowledge bone stock, slap together performer and 650 on for now. 86 is from you guys say will be a one I want to take time on to do right. Ran before I pulled but leaked everywhere. Wanna maybe go with magnum aluminum heads. Shame too, 86 heads were 302 j heads. 300 horse is a good learning start.
if you're that far in, throw a cam at it. nothing wild. but like a 360 2bbl melling is cheap as chips, or a basic RV or one of those white box summit single pattern jobbers. that with a performer and small 4bbl will run real nice.
Doubt anyone will have a deal for a 360. Let alone gas money and extra 50 lbs they bring with them. Spring fling has suprised me beforr though.
you never know what may show up in the swap. i know a guy with a complete magnum...
