i think i did 80lb ish on the last one .
i've been thinking about hitting it harder just to be sure (er)

So 86 ft/lbs it is. That is what the box says and I think ARP knows what they are doing.

I just got done running circles around the parts department people at my nearest Toyota dealership. If they didn't have a parts manager there I'd be SOL. I swear to god I had 4 different parts people try to help me with no luck, they were that incompetent. Parts manager comes along and tells them to move and for me to come behind the counter and says "Just bring up the screen, he'll just point out the parts." If I got a job there I'd be assistant manager in about a day.

Well after meeting Dan (ddmcse) I'm even less confident that I will be able to use this head.

He suggested that I post a pic and see what you guys think.

That's cylinder 6's cooling passage on the exhaust manifold side.

Will I ever get a good seal using a stock head gasket here?

You may just about get away with that, below is a pic of my head I removed when stripping down the engine to do a big end repair about six thousand miles after the BHG repair, probably due to the three problems I had. (That’s another story) You can see the pressure marks left by the stock head gasket extend quite a bit out from the cooling passage, although I'm not sure looking at you pic how far out the damage is on the left side of the cooling passage. One option is to have it mig welded and then re shaved, at least its not near the combustion chamber.

Wow Bill UK you always seem to have just the information I'm looking for. Thank you!!

Wow that head looks mint, I wish mine looked like that.

Yes the damage on the left extends out farther than the damage on the right. I'd say 2.5-3mm.

I was just saying that to myself about it not being near the combustion chamber. There is far greater pressure in the combustion chamber (180psi) than in the cooling passages (15psi).

Thank you for the input it is greatly appreciated!!!
