resetting tappets on vs v6 motor

[snowy213]

hi i found out my manifold gasket is bugged but since the car has high ks i have decided to do the head gasket at the same time could any one tell me if i can get away with taking the heads off then putn them back on an not having to adjust the tappets as long as i dont let any oil out of the engine to keep the oil pressure up or do i still have to adjust them???

The ecotec motor runs hydraulic roller lifters direct off the camshaft. They are not adjustable and will give the correct clearances once the rocker/pushrod assembly is all bolted down to the head. So yes, you can replace your manifold and head gaskets without having to touch the lifters.
