O-ringed head gaskets HELP!!!!!!!!

[5.0DuDe]

i need to know what the best O-ringed head gasket money can buy i keep blowing mine these will be the 3rd set form fel pro that i toast

i was really thinking about the cometic ones but i dont know which one is for stock O-ringed heads

can somebody give a part # or help me out

 

[BlackVert]

are those the fel pro 1006?

Blowing or leaking?
If blowing its likely your tune, and if leaking its bad installation the are a pain to line up just right on the cylinder head

The fel pros are top notch

 

[5.0DuDe]

which fel pro gasket are u speaking of

i neeed the ones for o-ringed heads

are they the 1006s

 

[4Jenna]

I was talking about the fel pro lockwires, pretty sure thats the part # but I quit running them years ago

 

[BlackVert]

the loc wires are #1006, i'm getting them for my heads because they are o-ringed too

Why do you guys opt for the lockwires over a MLS?

 

[5.0DuDe]

whats an mls

 

[4Jenna]

Multi-Layer Steel
Cometics are MLS, Fel pro also sells a nice MLS

They have no o-ring and dont have to spend the $$ to have the groove machined in your head, they have layers of steel that make up the gasket. They are the gasket of choice, were the o-rings were 4-5 years ago
They come in custom thickness, are reusable and seal like no other. Most hi hp boosted engines run these

i just bought my heads and they are o-ringed. i thought i had to use loc-wires. can i use mls instead even with o-ringed heads?

 

[5.0DuDe]

how about if u have oringed heads can u still use these

becuase if u can im going to order these things tomorrow

You would have to have the orings milled out

[5.0DuDe]

so basically i have no other choice then the fel pro loc wires

 

[4Jenna]

getting the heads milled at a machine shop is no big deal, but if you dont wanna do that then yes you have to run lockwires

It would take .010 thou at most to mill the o-ring groove out.

Why do they keep blowing... use or abuse?

depends on who did the work. i just saw (3 days ago) a set of cast heads that had to be cut .030 to get the grooves out.

 

[4Jenna]

very true, .010 is the norm...every head is iff

i would get them machined out, then go with the cometics. haven't had any problems since i put these in. and i don't exactly baby it either. used to blow head gaskets all the time
