Bingo. If you're gonna go through the trouble to build a truck engine to do actual truck stuff, build a diesel. My powerstroke has spoiled me to the point that I have no desire to tow or haul with a gas engine ever again.
That said this engine is already built by the sounds of it and you should go with the 2.02 valve. If it were a stock stroke motor I'd say 1.88 but let's face it, strokers ad displacement without adding breathing capacity (ie. Slant sixes) so open her up and let her breath.
Also keep the high compression. Premium costs about the same as diesel and you'll have way better low end.
