One thing that I do so that I can see if the if the pushrods are successfully registered into the tappet "buckets"...
On each pushrod I have rolled, with a blunt knife, 2 light grooves that align with the top of the barrel.
First groove is for compression stroke at TDC (both valves closed)
Second groove is for top of exhaust stroke at TDC (both valves open to some extent)
So one pot I should see both "first grooves" level with top-of-barrel, the other pot both the "second grooves"
Saves fiddling and jiggling pushrods that are already "in" but more importantly gives clear visual indication of any that are not "in" (i.e: could cause a bent valve).
NB: I "roll" rather than "scratch" the line to minimise creation of a stress raiser (although rods are only in compression)
Cheers
EDIT: the thread seems to have drifted from head removal to head refit. No harm done
