Gaskets

When using gasket maker opinions on Toyota 103 seal pack vs Right Stuff, also black vs grey Right Stuff. Thinking about going with right stuff only because it's available much closer then the Toyota dealership. I only have the tundra which is in the middle of major overhaul, maintenance, tune up and upgrades. (Changing/flushing out every fluid, valve,oil cooler, transmission, gaskets, cam & crank seals, several bushings, O,T,&A, filters, power steering return lines, leveling, 2"/1" lift, boots, control arms , shocks, coilovers, all ball joints, fuel filter, wipers, spark plugs ,ignition coils, pcv valve, O2 sensors, ABS/Speed sensors, clock spring ,new AT tires, rims, center Carrier bearing, new fog lights, interior lighting and floor mats back up camera and a over due wash/wax.) I'm at 250k and this better get me to 350-400k, cuz even doing this myself and finding deals on tires/rims it wasn't cheap
