No it will be approx £150 for gaskets and bolts.
Has it overheated.? Reason i asked is most garages will just skim the head for their own peace of mind when in fact most do not need doing. Hence why most cossies are running more compression. Only have the head skimmed if its warpped out of spec.

After cooling down, it could start easily and could be driven but no power.

And the most inportant thing is timing it up correctly as if you dont know cossie's you can get it wrong.
This is how it should be done. Notice the crank pulley is on the lug NOT the V groove as a pinto would be. Result would be piston to valve contact.

Let us know whats happening. It is possible with all that work done on it it may have a triple layer gasket.
Again if its 2wd and still on the 205 block i would advise if it has arp studs to remove and fit std head bolts. CHECK all threads in block for cracks.

Waiting for the Mechanic to open the engine .
Triple layer gasket ? Wow .. Why would anyone do that ? Isn't a thicker head gasket better ?
