i have been using the orginal honda one gor my 2.0 lsvtec i blew it twice due to stretch headstuds so now i am gonna get new headstuds

now the real question what the differnts in headgaskets


felpro (autozone) and orginal honda i mean my friends have used autozone no problems on other low boost cars

 

if its blown twice due to strech maybe you might consider going to 1/2 head studs for more clamping force.

 

i using some old *** arp headstuds getting golden eagle now

 

This topic has been beaten to death. Here's the deal:

If your block and head deck are flat to within .001" and your headstuds (ARP or Golden Eagle) are not stretched then it will have no problem dealing with boost, even very high boost (350+kpa). Past 400kpa there are different theories but I have seen personally that even high boost applications like that will stay together with flat block/flat head. A step-deck block .002-.005" couldn't hurt but I haven't seen the need for that even, because the factory MLS gasket has .010" of crush around the cylinders already.

All of the failures I've seen are due to:

-stretched fasteners due to overtorque
-less than flat block or head deck
-too rough of a finish (don't let a local POS machine shop surface your head on a belt sander, cause we don't use paper headgaskets) I'm always surprised because customers still show up with heads like that.
-Dowel pins too tall after a head has been decked
-stud not seated all the way in the block or a burr on the thread

 

thanks for ur advice what about the felpro headgaskets lol

 

3 words

Honda or Cometic

 

OEM

 

Golden eagle head gaskets which are factory modified gaskts work really good.I wouldn't torque any head studs over 90lbs but every have there remendy.

 

OEM Honda or GE (which are OEM Honda bored to your piston size)

1000 horsepower engines on those all day long

and no need for 1/2" head studs, you are wasting your time and money imo -- the standard off the shelf ARP or GE head studs will work just fine, again, 1000 horsepower engines on those all day long too

 

The last batch of GE headgaskets we received were NOT OEM gaskets.

 

I have an issue with My H at 89mm using a GE gasket. Reid.. Calling you now.

EDIT.. Good talk. THX

Ill be in touch Friday. Going Cometic this time with some New ARPs

 

How did they work out? Problems?

 

OUR GASKETS ARE OEM. WHAT ARE YOU TALKING ABOUT?

 

We only use Honda OEM head gaskets !!!

 

You should go ask somebody in the back.
The last batch i got also were not OEM. Just ordered some more and they were OEM so i dont konw what happen.
I use OEM or golden eagle in all engines i build.

 

agreed

 

Exactly. I dont know what happened there for a bit, but we got a batch of gaskets that didnt have the OEM part number stamped in the middle layer on the tab that sticks out (which ALL OEM ones are).

They seemed to work fine, but we decided to use that batch in NA cars

 

My very recent GE HG was a bored out OEM definately.

I have to take the head off, want to freshen up the studs as they are old and been used 100000000 times LOL. The last GE one I got the bores had actually compromised the seal ring on a cylinder or 2. Just a HAIR, but enough to where my motor is pushing coolant for no reason so it has to be either of the two as its a fresh build, step checked and head surfaced at a very reputable machine shop.

I want to try something else. At 87 and 87.5 I ran OEM with NO problems. I believe the cometics are actually punched out to 89, not bored, which is one reason Im going to try one. I really dont buy that OVERSIZE Cometic vs GE-OEM theres a notable difference other than that. Im not using any wierd thickness, just a standard thickness 89mm bore.

I have nothing BAD to say about GE, the sleeves are awesome (im running them), and it could have been a fluke with the HG :O) . Im actually leaning more to the studs being old and the head lifting a tad at 30+ PSI. This motor has never really pushed coolant before.

 

I have run both OEM and Cometic gaskets, and had good luck with both so far... Im running a Cometic on this new setup, which were gonna push a bit more just to see what we can get out of it... So we'll see

 

OEM bored GE here as well although I am not making huge boost. I have seen about 29ish psi on a 62 billet.

Clear out your PM's.

 

done

 

felpro gasket been in my engine untouched for the past 4 years of hard street and track abuse.

 

As far as torque is concerned, remember that H22 uses a 12mm stud (tq 90 ft/lbs) and B-series uses 11mm stud (tq 75 ft/lbs)

 

Yup I tq the old boat anchors to 90 Ft Lbs

 

****, I TQ my B series studs to 85-90 too
