okay ive had 2 4.0 inline 6's blow head gaskets now one in my cherokee and one in my tj now is their a better upgraded head that i could buy cause i cant find any or any tips y im warping heads cause i drive normal and i do go wheeling so im lost its getting exspensive lol please help me

 

go to quadratec.com (Quadratec's website) they have complete new (NOT rebuilt) heads, with completelly new valvetrains for $569.99 for the 4.0 6 cyl. or $379.99 without the valve train components

 

you said before about doing head gaskets very quickly...maybe you took shortcuts. Torque sequence, Cleaning Old Remains Off, etc...

 

um yeah 560 some is a lil to much and i take my time tourqe every thing right and the sequence and clean every thing but when u do it somany times its easy as hell

 

I know repetition makes a job easier, but are you sure it's warped heads? How have you verified this? Are you sure it's not defective head gaskets, or perhaps a warped block deck?

Blowing head gaskets can be caused by any of a number of factors, and you've only considered the head. Perhaps you've reused screws you shouldn't have (242ci cylinder head screws can only be reused once, you know - per FSM.)

 

X2. And are you using FelPro gaskets?

 

i used felpro, is that bad>?

 

I'm not aware of any trouble with Fel-Pro - or am I reading into this?

Victor/Reinz (Dana) is my preferred brand, but they're difficult to find. Fel-Pro runs a close second, unless I'm doing something exotic.

 

Not at all. Fel-Pro is a great choice. I would say your problems do not lie with a low-quality head gasket.

 

thought so

 

how did you remove the old head gasket off the surface of the head
