head stud location

[baptiste]

Hi, I don't have my books at my disposal.
Does anyone have a plan , schéma , diagram with the location of the 11 studs? (distance x and y between each stud)

Cheers

I machined sleeves from aluminum with a shoulder drilled them 1/4 inch bore. I bolt a known 11 stud head to a block drop the sleeves into the front and rear fastener holes put the whole mess in the milling machine (no DRO) and drill the pilot holes remove the sleeve and drill the correct tap drill size. Put a center in the chuck and tap a nice straight hole. I have done 998s and big bores with no issues. Steve (CTR)

you can use an 11 stud head gasket as well, as above, existing head is best bet though
