Hey Thanks Tom and Blown353 very much for the inputs. (my setup will definately be EFI, most likely using a BS3)
Tom you had said:
"...Also remember if you go with a o-ring receiver groove and your tune up is not there neither will your piston be there so there is something to be said about that gasket being the fuse..."
I'm guessing what you mean is that the "gasket-only" approach is "safer", in that the gasket will simply let go under these (bad tune) conditions, whereas if I have an o-ringed block, if I have a bad tune (ignition timing is way off, and/or I have detonation, etc) that the cylinder pressures can spike and damage the piston, etc., since the head seal won't let go?
A couple more questions:
If I were to just run cometic gaskets, is there any need for additional sealant on the mating surfaces (ie Permatex) (I would tend to think of the permatex as providing some compensation factor for surface roughness / extra insurance, no?)
Is any kind of specialized torque-down method needed for the cometic gaskets (such as the torque/hot air preheat/retorque sequence as shown in the article, for the o-ringed block and heads?)
Thanks again,
Rob
