felpro headgasket and head bolts
#21
I installed a Kumar bros gasket and ARP studs a month ago and its spitting coolant out by the temp sender. The original gasket was seeping out the front. I checked the torque and they're at the 125#'s ARP recommends.
Fel-pro has a improved design and old design available at my local parts store. I had them order the new design one in so I could look at it. If it looks good that's what I think I'll use. @ $51 I think if Fel-pro supplies cummins then it should be good.

I would have to agree ... done many Cummins engines and the " aftermarket" gaskets just dont hold up like the oem in this case ... done plenty of isc,isb,ism,isx, and older models like the big cam and such and the oem is just better.... 20+ yrs ... i wont lie , not like O'Bummer

I'm not having any issue with the gaskets fire ring. It's spitting coolant out. I'll know a lot more once I pull the head off. I haven't opened the fel pro gasket yet but looking at the you tube video I'm confused as to why the cummins one is so much better.
I already have ARP studs in it. Any input on torqueing them to 150# rather than ARP's suggested 125#?
I'll have to check into the o-ringing.

Kumar VS Fel-Pro
The kumar gasket slid and tore. I lowered the head with a cherry picker so I don't think I hit it. However I'm not going to say it's not possible.
The rtv lines on the Fel-Pro are twice as wide. The Fel-Pro is also of better quality (holes lining up)
Time to go buy a Cummins gasket. I'm anxious to see the difference.
I put pics on my build thread in 4BTswaps. They are too big of a file for here and I suck with computers.

The Cummins head gasket is made of a.stronger material than the others....... I ha e put many side by side along with a blind test with other mechanics and no one has bee able to tell the difference , That being said, the engines were buttoned up and the oem Hg is still running and the other ........ well it tossed a rod out the side and is no longer with us .... You may get lucky for a bit .... but is it really worth finding out who's right ?
