long term fuel trim and vacuum ?
Installed ls6 cam and 241 ls1 heads with studs and mls gaskets in prep for turbo kit.
Long story short is now only have 15lbs vacuum at idle and the long term trim on drivers side is +9.38. I cant find vaucuum leak anywhere think i have to pull the head and get the valves checked on the drivers side? The long term trim on the pass side is around zeroish.
Any help would be great.

Sprayed every possible place 3 different times. Hooked 3 diff. vacuum gauges ect.... Cant find the slightest lest. Swapped O2 sensors and still no change. I think maybe I will tear her back down and redo the Head gaskets....I cant really think of anything else at this point????
