The LT4 knock module is different, and I'm not sure that it's a bolt-in for the 94-96 PCM. Not sure beyond that.

[jmd]

head assemblies, intake, cam, roller rockers, gaskets, knock module, ...

If you want to go all the way then you need a throttle body, plug wires, timing cover, new opti spark, timing set. Not to mention the plastic valve covers and I'm pretty sure the injectors were also bigger.

You can get away with swapping out the heads, intake and camshaft though and reusing all the other stuff. I think the cam dowel is slightly shorter as well, you might have to file or cut it somewhat. It's been awhile:)

Or you can have your heads and intake ported and get your intake powder coated and noone will know the difference, other than the EGR valve.
