Ok, head gasket ordered, rings for pistons ordered and new 7/16 rod bolts ordered. I figured I'd better do the rod bolts cos they have been used 3 or 4 times now and are probably stretched too much. My Haltech cable arrived this morning so I can get to tuning the car slightly and when all the stuff arrives I'll sort the engine out. I also bought a bead blasting cabinet yesterday with some glass bead to prepare the pistons, so everything is set in motion to get it done.
