Hi i have a very good set of heads i just got for my 83 aspencade and in the manual it says to line up the timing marks on the pulley and the mark on the rear cove piece, it does not say anything about how the valves should look or once i put them on and set the timing mark will they open and close properly without hitting the pistons. that what happened to my last set i did not set timing correctly and I am scared to install them again and do it wrong can someone please help?

There are timing marks on the cam pulleys that need to be lined up. Because of the valve springs they often want to move as you fit the belts. Be sure everything lines up, then turn the engine over by hand for 2 revolutions and double check the timing marks. I believe there is a how to article on this site you can reference.

Ok, I guess the next question is do you line them up and put the belt on and adjust tensioners? You also have to make sure the timing mark in the little window is at the T mark correct?

Yes. And yes.

The cam wheels have the word UP on them. When you have the correct timing marks lined up, the word UP will be at 12 o'clock.

The tensioner spring sets the tension. Do Not push the tensioner tighter than the spring pressure or you'll get squeaky belts from too tight belts and possibly burn up the tensioner bearing.

That might have been true 35 years ago when the bike was new, but those springs no longer have anywhere near the proper amount of force to correctly tension the belts.

The best way to do it is to use the belt deflection technique, where you measure the amount of deflection in the belts and tighten the tensioners to adjust.
