Everyone has been a great help, but......still trying to complete my motor instal (will post photos soon). Have some final questions:
Headers- Guess I'm stuck with Edelbrock shorty's. for a stock hook-up with my exising exhaust. Would ceramic coating or wrapping the exhaust with tape reduce the temp's under the hood?
Header gaskets- Don't want any header sealing problems. Looking for the best header gasket. Any suggestions?
Header bolts- Need some input on locking header bolts.
Jet size- For a Holley truck avenger 670 @ 3,500-4500 ft. Will be runnung the jeep at 1,500 t0 7000 feet elev.

Edelcock shorties are nice, stay away from header wrap unless you feel like buying new ones all the time.

I just use regular header bolts.
Jet size, you'll just have to experiment.

+1 on the Remflex gaskets. With those, normal header bolts will be fine, just re-torque after a couple of heat cycles. Don't wrap as the wrap holds moisture and rusts the headers. It's fine for a race car that never sees rain, but not for a daily driver.
There will be no one jet size that will work from 1700-7000 ft elevation. Holley recommends 1 jet size smaller for every 2000 ft elevation gain. When I moved from Chicago (600 ft) to Denver (5500 ft), I ended up going 4 jet sizes smaller on the mains, and 6 on the secondaries (done with an exhaust gas analyzer). My Holley (600 CFM list 1460) was very close right out of the box for my 360. They're jetted for 70 degrees and sea level out of the box.

I have the eddy 600 and do most of my tuning with the needles because you dont need to take the carb apart. you can span a few jet sizes with the needles so it works out for me

Looking into the Remflex gaskets. I will check out the holley needle option for the truck avenger. What can anyone tell me about the coating choices on the Edelbrocks? Sounds like high temp. paint vs. ceramic. Anyone have any feed back on the " under hood" heat savings on the ceramic ones.
Can't believe all of the pics I took on the digital have been misplaced.........Will try to find some back-up's and post. Thanks.
