Look thru the online parts catalogs. FelPro, Victor... satisfy yourself. Gather the specs. If I remember correctly, the major manufacturers all went to what is essentially turbo spec gaskets. They are all better than what was available in '88 or '93 due to advances in technology. Also research using 6.9L gadgets vs 7.3L gaskets (basically unplugging the water ports at the lower ends of the head) which adds to water flow. There are some great in depth discussion on that here. The fire ring diameter is the same for all recently made gaskets as several on the board have verified. Napa is a vendor not a manufacturer. Like most stores that have in house brands (Car Quest is another), their parts are reboxed from somebody else or rebranded from somebody else. They used to be good at picking the best parts to rebox... lately they have been slipping a little. But so have the others, trying to maximize profit by minimizing costs. It really pays to know who actually built the parts before you plunk down the bucks. If Napa is reboxing FelPro, that's good. Better than some noname part from China.
Thanks fellas.
