can anyone help how easy and what happens if the tappets are set wrong

Did you adjust them when the engine was cold ?

if they are mechanical, the shims need to be put in the right place and you need to do the valves in order.
valve 1 inlet - valve 4 inlet
vavle 1 outlet - valve 4 outlet
valve 2 inlet - valve 3 inlet
valve 2 outlet - valve 3 outlet

sure thats how you do it, but the shims need to be put in the right ones, you need to feeler gauge each one

the numbers stand for the cylinder

yeah left the bonnet open for 4 hours the enginge was stone cold
