They'll fit in a 4th gen. I've seen a 4th gen with a big chief headed, tall deck 698ci, BBC. The intake manifold was a little tall, but it all fit between the frame rails. There was a little notching involved for header clearance, but it fits.

In reality, running these heads is probably going to cost you upwards of 5-6k after you figure a new set of rockers and valvetrain components, plus add in the cost of a new intake manifold, as well as exhaust manifolds and it doesn't make much sense considering there are quite a few options for badass cylinder heads on the market that will work with your current configurations.

Arias Hemi Chevy cylinder heads includes:
1 pair of cast aluminum Hemi Chevy cylinder heads completely assembled with premium Stainless valves, seals, springs, retainers & locks,
2 pair of Rocker arm assemblies with billet rocker stands, heat treated rocker shafts, heat treated intake rocker arms with needle bearing tips included with tool steel adjusters.
1 set Manton push rods with tool steel tips
1 pair cast alum. valve covers & breathers
1 set spark plug tubes and seals
1 pair of steel header flanges
1 cast alum intake manifold (blower or carb.)
1 cast aluminum valley cover gaskets for heads, valley cover, hardware for cylinder heads valve cover and breathers
Cylinder head kits assembly and dyno tested
available from $18,900.00
I think that price is for a BBC but still...
Let's not forget something-it's a $20K option for custom Hemi-Chevy heads from Sonny Leonard that are legit-they use a heart shaped chamber. The Hemi chamber itself is crap, very inefficient. The real trick is to make the valve design work in a heart shaped chamber like SL do.

So for close to $19,000, it makes how much more power than an ls7 head? Hell, you could get a pair of c5r heads and intake for less than that.
For $19k, I'd call up Kateck and see what that $19k could get me. I'm guessing around 600 rwhp and 454ci with a badass set of ls7 heads.

For that kind of $$$$ you might as well go ahead and purchase a real hemi and be making more HP/TQ than this off the wall configuration not to mention having a much kooler and easier to maintain engine. LS engines are nice but hemi's still rule. I mean a real hemi not this crap motor that chrysler is trying to call a hemi now days.

I think the days of 400hp with 8mpg are dead. The LSX motors are far more efficient and reliable not to mention cheaper, easier to tune and are still being constantly updated by the aftermarket. How exactly would a classic hemi be better?
