The only thing I can see different on the heads, is that the egr will need to be plugged. Other then that I can't see why the left and right don't switch. I just started at Chrysler about 2 months ago though, so I'll track someone down from the engine group to verify.

I talked with Bob at modern this week about the heads, they can do them but the early heads don't have a ton of valve spring options. That might push me to the later heads (which flow nearly 50cfm out of the box better then the early heads also). So we'll see what I end up doing. Just mocking up for now, but nice to see how easy it fit.

The heads don't look to have enough meat in the casting to Redhill the pattern.

I already had the right width Dana with disc brakes ready to go, so it didn't make sense to start over with a 9" or 61.

The car should run better with some more cam anyway. It's got its tongue hanging out on the big end right now as it is!
