Re: valve spring question
The funny thing is Comp recommends the 926 for all of their Xtreme Energy 4x4 grinds for the 4.0. Nobody's thinking over there.... They do not belong in a mild mannered daily driven motor.

Re: valve spring question
Correct me if I'm wrong - it's been a while since I shopped for cams - but aren't those recommendations for a 4.2L? They say the cam fits a 4.0, but I believe the spring specs are just for a 4.2. (which have a taller spring height).

Re: valve spring question
Yes, they are to fit the 4.2L head. Comp Cams doesn't care.
