What head to use on a 2000 4.0 stroker block. 7120 or 0331 Tupy?
Posted: May 17th, 2019, 4:12 pm
I have a built stroker but in need of a head.
The stroker build is a block (Cast # 5301449 ) from a 2000 Jeep 4.0 XJ Cherokee.
The crank and rods are from a 1988 4.2 and is bored .30 over.
I have access to a 1994 4.0 7120 head but not sure if it will work on the 2000 block.
I believe the stock head was a 0331.
Will the 7120 head work or do I need to find a Tupy 0331?
Also if I have the head rebuilt, should I use the heavy duty Mopar springs or stock?
What year intake would work best for my configuration?
Thx
