So i'm thinking about going 408,
But the heads i was going to use for my stock cube 6.0 are gonna be a little small for a 408 i think. Was gonna go with PRC stage 2.5 5.3's

You guys think they'll be to small for a 408?
what head would the recommend?
Motor's still in the planing stages right now so i'm open to offers.

I believe there were a couple 408 setups using the 2.5 5.3's, if you check out the sticky in the dyno section.

Yes with the right cam the L92's should work but they are $1800 anyway. PRC has a 237cc that is worth looking at as well on top of a 408. I will be carrying PRC shortly.

Example for you: 408 with PRC LS6 stage 1 heads and an MS4 cam put down 470hp out here and 420 tq IIRQ. I think he had an Ls6 intake as well.

It's a budget choice.
