Blown head gasket / Need ARP studs?
Blew a head gasket last night after 8 hours on my fresh rebuild. It happened after two WOT(5 seconds or so) pulls. It should also be noted these were the first WOT pulls since the rebuild. I was running a new stock HG and new stock head bolts (torqued per manual). Now after reading the various torque and stretch issues even with brand spanking new head bolts I'm leaning towards the ARP Studs. Just a little more background: Block to head mating surfaces were faced ('08 RXP Block) prior to HG install, I'm running a block guard, also still have a closed loop system. Everything else listed in sig.
Should I be looking @ anything else?
Does anybody have the ARP model #'s as I'm guessing I could get them a quite a bit cheaper through my speed shop than having to paying Riva to put them in a different box.

As for the ARP's their is no part number from ARP. The size you need is only offered in ARP2000 material and its expensive.

i always use stock head gaskets and bolts on every motor i have ever messed with. now these have all been cars/trucks, but translates to any 4 stroke motor. the reason being is think of your head gasket as a fuse, if something goes wrong, the fuse will blow, just replace it and its good to go. now if you started using stronger gaskets and/or ARP studs its like taking that fuse out and just putting a wire in. if something fails, there is no weak point to give. so now instead of you just having a blown head gasket, you now have snapped rods and a hole in your block.

if it was infact only 5 second WOT pulls i doubt it got hot enough or had a detonation problem that caused the gasket to blow. im going to say the block or head isnt square.

The only reason I knew something was wrong is because the temp alarm came on....I instantly shut her down and popped the seat to find the coolant jug empty....(I verified the oil and water level before I set out yesterday). I just drifted down river to the next boat ramp and loaded it from there after having a buddy grab my truck and trailer. Upon further inspection on the trailer I see oil / coolant seepage between the block and head. I pull the spark plugs and they have coolant on them. That's when the tear down began. The head gasket didn't have your typical blowout or track marks but the you could see exactly where it was seeping in and out when looking on the block and head surfaces.
suck my wake you have a PM from me
