Hi
Where is the best place to buy a head gasket set for the sprint. And should I use hematite blue on the head gasket.
Also when refitting the head to the block what do you use so all the bolt holes line up as there are no dowels.
The car is not on the road at the moment so when should I retourqe the head.
Any other tips for refitting would be great.
Thanks
Mike.

If you want a genuine Payen gasket (recommended) Rimmers have some. I bought one recently and looks authentic (there are so called Payen being sold that are not made by payen. (In fact Payen do not make them any more so whats out there is new old stock)
In the workshop manual there are dimensions shown for the dummy studs to use as guides for the head and gasket.
Torque the head and run the engine, then next day when cold, slacken one at a time and retorque. Then after 500 miles repeat :)

Dry, no sealants.

It looks as if I am going to have to replace the head gasket on one of my 1500cc engines so is the recommendation Not to use any hermatite blue on that like a sprint head?

Hi
Thanks for the replys
Are the dummy studs in the manual the same size as the ones in the engine. Would I be able to cut two down to use.
Thanks
Mike.

I use two of the head studs inserted in the head bolt holes to align the head.

Yes the dummy studs are made from either the bolts or studs, cut down and a hacksaw cut in the end to remove it (length of stud is less than the height of the head). Too long and the head hits the inner wing before it gets down to the surface. The dimensions are in the workshop manual which I dont have access to right now, but can find tomorrow if you need them still.
