your lean put some bigger jets in it and thry that alos do the vacume leak check start it up let it idel and take some wd40 and spray around all places you could possiblty have a leak ie carb base and intakre gasket area if you have a leak it will pick up rpm when the wd gets in the system

one of the biggest factors in exaust temps is ignition timing. double check your timing. if it checks out ok...triple check it

If your running 76 jets i wouldent think your running lean, unless your running some serious heads. my buddy had this problem and it was the intake not sealing good.

Rule of thumb is when 2 pipes are red, you have a vacuum leak. Make sure all the rubber plugs are on the carb first, then check intake manifold plugs, last is intake gaskets. Your problem is one of the 3.

Check timing yes. All the fuel is not getting burned in the cylinder so the burning fuel is going out through the headers. If its not timeing it could be too high of octane fuel. Low compression engines just waste fuel with higher octane.

Thanks for all the help. Turned out to be the warped carb adapter not sealing.
