I have a head that i pulled, and i want do do all new gaskets and seals and do a valve adjustment if its possible without it on the block.

 

yeah you can do it off the block!

What made you think you couldn't have done it?

 

youre supposed tp have the cylinder at tdc

 

the reason you rotate each cylinder to TDC and adjust the valve lash when that cylinder is at TDC is because thats when the valves are in the closed position and not being pushed open by the cam/rocker. So just make sure you use the same timing marks on the cam gear and rotate the camshaft like it states in the manual so the valves are in the closed position when you adjust the valve lash for that cylinder.

 

ohh gotcha. so couldn't i just flip it over and make sure the valves im doing are closed?
