243's, long tubes, 212/218 low lift, tune? I'd consider adding 4.88's or 5.13's later on as the tire size increases ...

I've got another car that I go fast in, really just looking for some more grunt for when it's pulling stuff around.

That would do well. 243s would be a nice bump in compression

Depends on how much of a compression bump the 243s give you, are you okay with switching to premium fuel? Then I would say that's a good combo. If you want to stay on regular unleaded, just throw in the cam and leave the 317s.

I already run 91 in it, so that wouldn't be a problem.

Would I need a looser converter or would the factory one work OK with that cam?

212/218 is a baby cam for a 6.0. No converter necessary, but it wouldn't hurt

A converter is always a great ugrade and especially with a cam. A 2800 or 3200 will be nice for pulling with that cam. The truck will also **** and get empty. Big trans cooler and let her eat.

As for 5.18s they would be a bit much unless you are on a larger tire then stock.

Thanks for the feedback. Going to pick up some 243's on Wednesday.

I'd only do 5.18's if I go up to 37's again.

Should pull really really well. As mentioned more compression would be good. If you want to keep your heads milling the stockers is a cheap simple option.

Well, ****.

These heads I agreed to buy were 706's, not 799's. It was a 3 hour drive, and the guy waited up until 9PM to sell them to me, so I picked them up anyway, but are these worth a damn? Preliminary research suggests that they will still increase compression a bunch, but have smaller intake and exhaust ports, which will choke the truck after 5000rpm or thereabouts?
