i recently recieved a 1990 1500 5.7L truck from a older guy, its heads were reseated..but the guys who was putting it back together just walked off...and the rocker arms need to be adjusted but the intake is put back together...timing is right...is there a way to adjust the rocker arms without taking the intake back off?

when it loads... click on the engine overhaul link... and then look for the rocker arms link...

that should help a lot.... it's free... it explains... it has pictures...

more questions ... that have been answered thousands of times.. do ask....
