I need help ;-)
Porny:
--- Quote from: "gtomo2" ---there are four studs missing two have stripped out the thread one is snapped half way inside the head and one is snappedd flush with the head.
But i dont have the kit to drill them out and re thread them plus got a new seconed hand head with the car.

Shame the two have snapped inside the head....
The striped ones could be re-drilled and helicoiled very easily, but the snapped two would be slightly harder.
If they'd snapped protruding from the head, then you can usually get them out by welding a bolt to the broken section... the heat of the welding usually helps them out.
You could probably drill the two snapped ones quite easily... would usually be easier than removing the head. The problem though is access... you need to make sure you drill straight - which is a bit awkward with the head still on the engine/in the car... at least if you want to make sure you do it properly.

They are on the easy toget at side of the engine. but just never done it before plus not having the kit. plus like you say dam hard to drill stright when the head is at a angle. and alloy is so easy to drill through which would be my luck
:roll:

and ou have bought the gasket set

Sort of....
But do you know if the other head (the one your leaving on) has every been skimmed?? You could end up with a different compression ratio on each head, which isn't the best.
Or, has the new head you've got ever been skimmed?? Again, you could end up with the same problem, but in reverse.
IMHO, all I'd do is check the new head is flat - which you can do yourself with a flat edge and go from there. (as long as the face is in good condition)
If you want to do it properly, you need to take both current heads off and measure the piston/cylinder volumes, and then measure the volumes of all 3 of the heads... and calculate the Compression Ratio.
