My manual shows the intake to head torque setting to be 25-45 ft.lbs. on one page, but on another - where many other torque specs are listed in a column - the spec is 35 ft.lbs.
Since I've been screwing on these engine for a lot of years, I have developed sort of a "feel" for torque. Pulling the intake bolts up to 45 ft. lbs into aluminum heads pegs my nervous meter, even though the bolt holes are heli-coiled. So I chose the 35 ft. lbs. setting rather than trying to pull them to 45.
I've never been able to find the spec for the intake manifold RUNNER bolts, so I use 35# there too and my nervous meter never went off as I was doing it. 35# is probably at the high end of the range though.
20 ft.lbs. seems low, but, absent any contradictory information, I'd go with it too. The runner bolts are of a smaller diameter so, theoretically, require less torque. I just hit them over and over to make absolutely sure that 20 holds.

I'm NOT nuts! Reason for the bad leak... I have two left runners. I called LPE today and spent a while on the phone with Tim Dyer (need to buy HIM a beer after all the q's I've asked...). He got a set from somewhere and looked at them and we confirmed that I have two of the same runner. It's also obvious looking at the gaskets sitting over the egr ports that one doesn't fit... leaves about a 1/2" hole outside the gasketed area 
. Bad assumption on my part, I guess, that I had been sold all the right pieces...
Anyway, project has to go on hold for a week or so while he tries to get Accel to send me a new pair on exchange without charging me.
Maybe now it'll work...

hey Hey HEY! All the shrinks swear up and down that I'm clinically sane! Or was, at least, when they let me out.

Gah, I just want this project OVER with. It feels like a bad government contract at this point.

Don't feel too badly about it. I've lost count on how many times we've suggested to others to check certain things, then to have them come back and post that "everything was checked and is "fine".
Then, later on, he posts that the very thing he said was "fine" WASN'T and it was the cause of the problem.
The he apologizes for causing all the confusion.
Just seems to happen a lot for some reason that I still can't put my finger on.

Scorp508 - you said your SR has the bolts inside the plenum. What kind of heads do they have, what size are they, and how do you space them away from the walls of the plenum? I'm having spacing issues to the point where we're not going to modify the 8 outer bolts and there's some question about two of the inner ones.

The two that I *really* want to do are the inner driver's rear (by distributor cap) and inner passenger front (by TB) so I don't have to pull those two items to take the plenum off. We're investigating allen-head bolts like smaller versions of what holds the runners to the manifold.

Yep! God it only took 2 years for me to realize it! *edit*
Can't exactly remember the size of them, but they're just a six-sided bolt head.

Rich,
Sorry to hear you are having so many woos with this set-up. But I'm convinced from reading this that you should see the light at the end of the tunnel bright and clear.
You have been vetteless for tooo long IMHO. Maybe some weekend morning you can come over and we can visit a nice windy road. I have cones too. I have discovered, that is the best use for a Corvette. There are a lot of Country, curvy roads here.
