Check for vacuum leaks.... PB booster,, trans vac modulator, carb base, intake,,, corvette vacuum operated acessories (head light doors) ( A/C...heater duct control)

the intake bolts WILL NEED retorqing. (by hand)

I run a cold manifold...but I don;t drive in the winter. ( and my engine combo is much more radical and racey..
(its very drivable and smooth 'cause I spent the time to dial it all in.)

On your car....I would start with one side blocked off and one
side with a 1/2" hole in the intake gasket so you have a "warm manifold"... A warm manifold is easier to tune correctly. A Hot manifold, too hot is a pain..(full open heat risers).. a cold manifold is harder to tune for especially this time of year.j

Its all about finding the sweet spot.
Yah, in had verified with a stop my tdc awhile ago, all was good there. This is about as much cold as the car will see, bout 5 and it seems to run fantastic with the riser blocked. No vacuum leaks, headlight leaks were many when i first got it home and that was the first thing I addressed.
