Performance camshaft.

[Strokermjcomanche]

Looking for a performance camshaft that I don’t have to modify the seats on the head. Anyone have any options for me? Most of my options are not in  stock because of shortages. 
 

95 4.0 , now a 4.7 , 802sealed power pistons . I plan on running stock valvetrain if possible.

The camshaft should have nothing to do with modifying the seats. That’s just the valve springs that are used that may require a specific installed height or a narrower ID to accommodate for a thicker spring wire. There are several off the shelf options for aftermarket springs (see latest in-stock Mopar offerings at the bottom of this post). Good stock springs are good for about .44 lift on the cam with regular 1.6 rocker arms. I personally prefer the stock renix-95’ cam with some 1.7 roller rockers. The Mopar purple cams were nice too. Good vacuum and full width cam lobes instead of those little narrow ones found on most aftermarket cams. Comp just came out with some new 4.0 cams though also: https://www.compcams.com/xtreme-4x4-197-201-hydraulic-cam-for-jeep-40l-1964-98-cpg.html

 

That cam is very similar to the original Mopar 229 cam. You could possibly get away with stock springs depending on the valve weight. 
 

If you do need valve spring for a higher lift and don’t want to machine the seats to use LS or comp springs than use these:

What kind of performance? Low end grunt power, or high RPM horsepower?

If comp had that cam in stock that’s what I would have bought . I can get the comp springs that look like the mopar ones with the dampener springs, but the head supposedly needs machined which is strange because they look identical to the mopar springs.

I’d prefer low end grunt , to mimic  my black truck . But I’d take a low to mid range as well

 So you're looking for what is generally referred to as an "RV" cam rather than a "performance" cam.

i believe the comp springs have almost the same installed height but the spring itself is thicker so a narrower seat ID is required. The Mopar springs are drop in though. That comp cam hasn’t been released yet but should be soon. 
It’s not really the ideal low end cam your looking for though. @Eagle is right. You need more of an RV style cam
