Kraazy_Cooter · **Cometic vs. Mopar Performace head gasket**

I see that turbos unleashed offers different styles of headgaskets. I have used fel-pro for years and never had any problems, but I am looking to make more horsepower than I have before. I have read that anything but the mopar performance gaskets would just give you problems. So browsing through their website I noticed the cometic gaskets and for almost a hundred bucks a pop, you would really have to be comitted. I am not looking to exceed 20lbs of boost, could I get buy with a mopar headgasket?

From what I have seen and heard, the mopar gaskets are perfectly fine for what you want to do.

20 psi, you will be fine with the MP 005 gasket. For extra insurance, run ARP studs. I happen to have a band new set for sale, $85 plus shipping.

**Turbo Joe** · 03-10-2007, 08:21 PM

but you can't re-use a Mopar gasket.. a cometic you can. i speak from experience.

Brian Putman · 03-10-2007, 10:12 PM

You should be fine with an MP gasket @ 20psi and a proper tune. I'm going to a Cometic though. I ordered it direct from Cometic. It's a custom .036" thick gasket. I'm also going to ARP studs and doing the #4 coolant mod after I lifted the head @ 30psi and the MP gasket let go in a big way!! It was doing some serious hauling before it blew!!! Now I have to make it live at that power level.

I have a cometic on my 2.5 and have no problems and have hit 20+ psi. The only thing is cometic gaskets do not like rought finishes. To do in right your head and deak should almost be a mirror. "A surface finish of 50 RA (roughness average) or finer, is recommended for a proper gasket seal. Anything rougher may conflict with the gasket design". "MLS head gaskets reduce bore distortion and withstand extreme cylinder pressures." I got mine from fwd for a $100 or so. The arp head bolts are a real good idea too, head studs be a little much for your goals.

Studs are a great addition at any power level, the biggest bonus is there reusable. Why by a reusable head gasket and throw away bolts,

moparzrule · 03-11-2007, 06:37 AM

The mopar gasket is fine for anything up to around 350 WHP, I was running 300 WHP and never popped one even with the mopar bolts re-used 3 times. I used Gary's torque test, on the 1/4 turn set the torque wrench to 100 ft/lbs and it should hit that before the 1/4 turn is done. If it doesn't, the bolt is no good. Well, that method works great because some people are scared to use mopar bolts twice, but I used them 3 times before and the gasket never went running 22 PSI and 300 WHP.

ARP bolts will do fine they are not a throw away bolt. Studs are nice if you take your head of your engine every other weekend and do not mind taking your hood off also to get it off.

Wrong, ARP head bolts are torque to yield and are throw aways. Only the studs are reusable.

Why do you have to take your hood off when using studs? have you actually used them before? I know I have never taken off my head as well as others. There broached so you can install them and remove them, just like bolts.

What??? Dude you are retarded. As simon said about the bolts, the ARP's are alos torque to yield and are throw aways. Also, the studs don't permanently attach in the block or something you can get them out easily and pull the head right off. I also think there's enough clearance with the hood on to pull the head anyway.

I have been around many engines with ARP TTY bolts that we have reused no problem. And by reused I mean no more than three times the bolt stretch is not a whole lot. But I will also say I would never reuse them on my engine. But as far as me being retarded

So as soon as some one jumps in on me O by all means chime in even if you calling me out on something you have done!

And as I said I do not reuse them on my engine but the original post

He is talking about a hundred bucks a pop being a commitment for your engine. So to me this doesn’t sound like some one that pulls his head ever weekend, or wants to put money in his engine.

Also innless this is a race engine that you are rebuilding every x amount of days , I do not see why he should ever have to pull his head off any time soon .

But anyways I do agree turbovanman Studs are a great addition at any power level, the biggest bonus is there reusable. I was not disagreeing.

Thank you for your time.

Hello? I was using mopar performance bolts you used ARP's. Your quote about ARP bolts was ''they are not a throw away bolt''. You are still retarded.

88jbody · 03-12-2007, 10:00 PM

My point was Gary's torque test still can be used. like i said i would not do this no my engine. Nor tell anyone that puts money in to there engine to do so. If you are looking to argue, i suggest you go else where. I am not looking to get into a pi$$ing match over somthing so stupid. I agree the arp bolts are not MADE to be reused. Now are we all happy.
