And it was going so well....
I fitted the inlet rocker gear and was about to fit the exhaust rockers.
Then I put the right-hand pushrod on, turning the engine with a spanner on the alternator nut.
Watched the valve opening, then it locked.
With the adjuster fully out it will turn-over completely.
This is a head off job now.
There could be many reasons for this to happen, just about everything is new.
I'm thinking, wrong camshaft, wrong followers, wrong pistons, etc.
Any thoughts?
