Does anyone know which head bolts will require RTV sealant when re-installing the heads? I think it is the lower bolts only but i'm not sure. Also, Is it good practice to lube them first, then put the RTV on top of it or do the opposite?

Also, do other fasteners require sealant that may be in the water passages - exhaust manifold studs? intake manifold?

I want to get this thing back together and don't want to screw up. Thanks for any help

I think a couple of the bolts by the exhaust go through water passages. The ones up higher are not and do not use sealant to my knowledge. Here is a good thread on another board that should have all your answers. That is the Poly 318 Yahoo group.
