My credo
It is what it is
Can you use 4.0 heads on a 2.9 motor
 
No. Forget the specifics offhand, but they don’t match up right. Think it was bore size and/or intake issues. Also 2.9 used adjustable rockers and 4.0 didn’t
 
+1 ^^^
No you can't
 
ok thanks
 
Yeah, I had that thought too when I started getting a collection of 4.0 heads and a shortage of 2.9 heads, lol
