A basically stock truck with injectors, box exhaust... and a properly torqued headgasket is good for 500-600hp on twins. the limit is about 80psi of boost before problems come.

80 psi with a stock head gasket?

Mark & Stakeman,
I have heard of the stock gaskets standing up to even higher pressures.
Collected from personal experiences and from two top level "Service" Tech's at Cummins here are the tips to long life with the OEM style gaskets.
1. Absolutely, Positively let your truck get to normal operating temp before having a Heavy Fueling Foot.
2. Absolutely, Positively let your truck get to normal operating temp before having a Heavy Fueling Foot.
3. Refer to rules 1 and 2
4. The above and keeping Charge air temps as low as possibe (which some Twin systems actually do better than a B-1 !!! Yes it's true!!) This keeps combustion under better control with less pressure spiking (And what I call thermal load). This is why there are reports of the cummins racing teams running 100+ psi with stock gaskets.
5. Propane is great as long as you don't over do it. During R&D of one of my early Propane systems I blew a oem head gasket "Big Time". I was injecting WAY TO MUCH propane.. The Engine was a hammering away then I had OIL Everywhere. Lucky Me this was on the way home from the races.

I have seen several and My Cummins Buddies have seen numerous Stock Trucks / RV's with Blown gaskets. They attribute 99% of those failures to improper warm up of the engine.
The stock Head Bolts stretch quite abit. They are Long Bolts and the Head is 6" thick. There is quite a bit of movement/Expansion as the metals come up to 180/190 degrees F.
On my truck I have "O" ringed the Head and machined a receiver groove in the block surface. I use the stock gasket (Which is a beautiful "Work of Art" and after checking the stock head bolts reused them. Since then I repeatedly put the gasket under high strain (Especially during overfueling with propane) and it holds like a champ.
"O" ringing the head is probably enough for most "Bombers" and for extra protection with the right tools the Block is easy to machine without removing it from the truck.
"Happy Bombing"

Are you trying to tell StakeMan that he needs to let his truck warm up before he sticks his foot in it. If so you may want to say it slower. Gonzo told me that StakeMan rode the short bus to school and it takes him a while to catch on.
;D ;D

<br><br>Don't tell me he also rode in the Back!?<br><br><br>[move][glow=red, 2, 300]"LET YOUR TRUCK WARMUP BEFORE STAKEING YOUR FOOT IN IT!"[/glow][/move]<br>P.S. Don't tell the school board But I "TUNED" one of our local school buses.... The driver says if he sees the mileage increase he will see about doing all of them. "Of Course to Save the City Money!!" <br><br>I did'nt think I should use Bombed in the same sentence as a schoolbus... Guess I did anyway [undecided]<br><br>Mark, do you have a set of twins setup for a BlueBird with a P/S or Cummins??????
