but he is using arp head studs now the reason why people pop an engine after forged slugs swap is either tuning or poor prep work

 

hes also using a stock head gasket and area doesnt race alot. even after i took my ported head off i re used my stock gasket and doged it 300 miles to go trade the car in and it was fine.

 

Then good as new

 

I think cylinder pressure has a lot to do with stock sleeves cracking also. Most of these guys running ported heads or TVS' or anything of the sort that will cause pressure to rise will be more prone to these types of problems.

 

I have the stock headgasket and arps on my ported head, I heard to many horror stories about the cometic, plus with people on stock block, head, studs, and headgasket pushing 28 psi both turbo and sc I would say the hg has earned its keep.

 

DING DING DING DING DING!!!!!!!

 

I've personally pulled 3 apr to find stock head bolts loose. it was always said to be stretched bolts....hmmm

 

Humm so whats the deal then? is cometic hg's the gaskets to use or not? because I wanna try to avoid this as much as possible for when I get my head ported...

 

I'm a fan of the stock head gasket. It's MLS just like the cometic and it comes with copper spray already on it and some gasket material already made onto it. The cometic has no rubber gasket material and is not sprayed with copper so it doesn't seat as easily.

 

I copper spray all head gaskets now, and since doing so, I have yet to have one leak on me.
Stock hg is suffice and cheaper

 

the reason most people have problems with the cometic hg is they dont follow directions jordan aka tennpen ran a cometic for a long time until a oil ring went **** up and he is the only one i know of that has stretched the stock hb bad enough to cause a leak

same here ive pulled a few apart and found loose hb

 

sleeves/the block have weak points, if the rings are not placed correctly in the correct area it causes extra stress and wears where it shouldn't be and when you have high compression along with that it blows a sleeve.

as far as the cometic goes... IF you install this right you have no problems..

as far as all the engine that are ******* up... that due to the fact of people don't know what the **** they are doing and have no business cracking open a block

 

I dunno..I cracked mine open without any prior experience. Runs like a champ

 

nice nice

 

Lol Thats funny.

 

luck.

 

Piston rings only go on one way. Pretty hard to **** it up.
