"Just installed rebuilt heads
"Just installed rebuilt heads on my Mercruiser 260. Ran the enigines today and the rebuilt one was overheating and had white smoke coming from the exhaust. The vacuum guage was showing in the "inefficient" range the whole time, not sure what that means but the other engine was showing in the "cruising" range. Bit of a rookie at this stuff so any help would be appreciated."
