rocker arm question
put the head back on my donor engine and put the rods and rocker arms and all that back on.
After I touqred everything I checked the movement of the arm with my hand and i noticed some off them move and some are soild.
Is this because the position of the pistons and everything or is something wrong?

it has to do with the cam position. with the lobe up it will open the valve (put pressure on the rocker) with the lobe down or in "relaxed state" it will release pressure and allow the valve to fully close and not hold tension on the rocker arm. if you torqued them all and the Timing gears are on then spin it over and make sure they all move.
sounds normal to me.

i didnt check before i took it apart. once everything was apart it all looked good. I did install new lifters but thats cause i rolled the engine on the stand before i took them out and they all fell out.
I mean theres really no way to put that stuff on wrong, i dont think.

It's the position of the cam shaft lobes....some are opening the valves (more pressure on the rocker arms), some are allowing valves to close (less pressure.
