Getting ready to put together the heads. In reading the factory manual about putting the cam cases on the heads it says: The camshaft is secured to the cylinder head with the

camcase. An oil passage in the cylinder head provides the

passageway in the camcase with oil that leads to the intake

rocker shaft. Oil from the camshaft is collected on the

opposite side of the passageway leading to the intake rocker

shaft to provide oil to the exhaust rocker shaft.

Sealing of the camcase is accomplished by using a thin

layer of three bond (1280B) applied in the channel around

the camcase edge. After the three bond is applied, the

camcase must be installed to the cylinder head and onto

the engine before the three bond has time to cure. Failure

to do this will result in oil leaks.

 

I had planned to assemble the heads one day and install them the next. But this advises against it.

 

Has anyone had experience doing this? Is it really critical to do it all at once?

I would try to do it all at once. when you torque the head bolts there will be a bit of flexing that could break the seal and cause leaks.
