ressurecting a sleeping beast..need help/advice

pull intake and plugs in plug holes spray wd-40 in each one leave plugs out and put car in gear 4th or drive rock car back and forth see if motor is locked. If not you could bend a valve or brake rings when trying too start the car then you should be okay.
I have saved mean motors that way had one that had set for 8 years did what i told you and bang she is still running with no rebuild just new upper gaskets .
Good luck with the car
