Aluminum Head For 4.0L

You are correct! We need the 06 for the CARB EO number. Vehicle mileage doesn't matter to the CARB.

This head is an Edelbrock design! We are not using anything from Patriot or Hesco! And under 50K miles is indeed to test the head on a "healthy engine".

Also with a CARB# of #D-592 and a retail price of very close to $2000.00.  With claims to fit 258 & 4.0 with the explanation that 258's have already been converted for the 4.0 Head.  The question really is whether there is a market for it or not.  

If I am not mistaken there used to be a 258 aluminum head that was marketed by Clifford some time about 15 years ago when the 258 was some what popular in off road racing that really did not sell that well.  Hesco  also the still Markets the MPFI conversion kit for the 258 for about $2800.00 which I understood Chrysler no longer markets and Summit no longer carries, the last time I checked anyway.  Which also has a CARB number which did 12 years ago when I bought one.  That is a turn key kit and runs well when you finally figure out what it needs to run. 

But if you just take those two and add the prices up you get about $5000.00 worth of performance options on a long stroke engine.  Which frankly is a lot of scoots to tie up in an engine that is under 300 cu in. 

The thought of building a performance in line I-6 with a carburetor I still play around with and frankly have a 232 sitting on an engine stand with that in mind.  And a Borla Header for a 1981+ 258 is about $500.00 for cat. # 17053.  Granted, if you have to ask how much you probably can not afford it, but the question still is?  Is there a market for one?
