I've personally rebuilt several engines. Were I to do this, I would look at pretty much a stock rebuild... unless I was going all-out, then I'd consider destroking first, deboring second, or maybe even cylinder deletes. I would not spend more to get light rods as that mainly comes into play at high rpms. I would have the head trued for a nice straight gasket surface and teensy compression ratio bump. I'd have a nice multi-angle valve and seat job done. I'd port match head to intake if needed. I put a windage tray in. I would consider a heavier flywheel if my driving style would be to short shift a lot; it would be especially useful paired up with a higher trans regearing. I would re-cam with a grind that's optimized for lower rpms, and also play with cam timing if that's what the cam grinder suggests. I haven't been ambitious enough yet to try to fab up some nice small diameter long tube headers(cuz the commercially available ones are all about high rpms) but that might help too. Coatings and such... who knows, I've never had that done, but if I did I'd probably do the piston skirts first- actually some of the new hypereutectic pistons come with it.
