Did a search on the site regarding cylinder heads and leakage from same and got some good info but I still have a couple of questions that perhaps you guys can answer. Engine is a 1978 F2, on a genuine Honda head gasket four of the oil return ways have a smaller hole which means that the knock pins and square section seals cant be used in those places, which confirms the info in the workshop manual that on the F2 these are a deleted item,does anyone know why these are deleted, have noticed that this point has been ignored by aftermarket generic gasket makers who seem to make all the oil return holes the same size,even though they claim suitability for the F2 engine, which means that for the F2 at least that four of them are far too large.
On the subject of torque values for the head,will follow those recommended but will do a three stage tighten down till final value then leave overnight and check again ,hopefully this will allow full crush to be achieved and full final torque value to be a true one.
What I am hoping to avoid is yet another removal of the engine to re-torque after initial running,is this a good enough method if not what do think would be the best way based on your own practical experience.
Cheers Mike
