Mine was fairly solid, might be worth tapping it back down where it is sligjhtly raised. I found my big rubber mallet worked making sure I tapped it all round including some upper blows on the intake side.
I also sprayed WD40 type stuff all around the dealing area.
Thanks Ted. I have just given it another good squirting and a firmer tapping with a plastic headed mallet to no avail. I havent tried tapping upwards from the intake side; i will try that tomorrow morning after an overnight soak. Where did you bash it upwards on the intake side?
I can slide a polished paint scraper around between the castings to the right hand dowel but not the left hand one so I guess its seized on the left one. Im assuming the dowels are supposed to be locked into the head as opposed to the rocker housing?
I would tap it down on the side where you can get the scraper in AFTER squirting in releasing fluid then I tap it on the inlets first as close as possible to the head working along the four intakes - I used quite a big soft but weighty rubber mallet that I bought years ago at the centre Isle in Aldi. If you have a lead shot type mallet even better as there is no rebound. Also squirt plenty of releasing fluid down the dowel areas and bolt holes. A tap from the left and right side might help. If the front side is slightly raised keep it back down working more on the rear and sides. Cups of tea in between tapping sessions and light or medium blows should work - plenty of decent releasing fluid not standard WD4o helps. I used some releasing fluid that car technicians use not bog standard WD40.
