A big expensive engine with shitty heads is gunna run shitty. A halfway shitty engine with good heads will run decent.

I would go with some ported 243 or atleast some 317s that have been worked alittle. If your gunna be goin with nitrous and don't forsee f/i down the road those patriot 5.3 heads would work nicely
