what ex gaskets to buy

the robbmcperformance starter is what looks like a direct drive which would have more space than the mini that is in their now which looks smaller than a regular starter. the tech sounded like a small amount of block deburring would suffice. I think I would be OK with wiring the kickdown all the way back if I have to eliminate the current kickdown linkage. I'm still considering the headers. the welder said wed for the welded ex manifold. excellent gasket info. RR
