would it be worth while to do both while i was at it? what about porting and polishing the heads while they are off?

if you can spend the time to not have thr truck running and want to do it then i would say get the P&Ped but to be honest you probably wont noticed a big difference at all unless you decided to go and put forced indduction into it along with other mods.. P&Ping a head or heads is more of a thing to do as a benifit mod... but defianately if i had the heads off i would do it for the hell of it....

If your going to have the heads off due to a gasket, odds are they are going to need to be resurfaced. .010 off on a decking can cause another set to go.. Might as well have the heads surfaced/decked as well as a valve job. It will get rid of all the carbon and buildup you have had over those 90k miles as well.

If you so decide to tear into it, then consider also going with the 4.0L OHV "rocker arm refresh kit" from Delta Cams (Part # F040 KIT) which is meant to address the issue of pushrod wear that the 4.0L is apparantly prone to. More on that issue can be found towards the end of this article, which you should be referencing in any case: Rebuilding The Ford 4.0L Pushrod V6

In most cases it involves shaving (milling, grinding, etc.) the bottom until it's flat.

Hey lifted97ranger, just to let you know, if you still think you have to replace the head gasket on your truck you should check the cylinder heads when they are off. I was replacing the head gaskets on my cousin's 99 4.0L ohv and we noticed that the heads were cracked and the coolant was leaking through the cracks, not through the gasket. The heads had a hairline crack between the intake and exhaust valves in three of his combustion chambers. We talked to a guy at a machine shop near us and he said that he has seen this happen to 4.0L ohv's before. I guess that coolant runs between the two valves, and due to rapid temperature change the heads can crack. he had to buy new heads, and he got a pair that had this coolant line filled in. Just wanted to let you know about this problem, so check your heads if you take them off.

yea i fixed the problem before the coil pack........
thanks for the heads up......haven't seen a drop in coolant at all......i dont think i had a head or head gasket problem......the dealership sold me the wrong plugs at the begininng of last year....when i went to a different dealership they gave me the correct ones....it fixed the problem...
