hey guys,i can use some help with decoding heads and intakemanifold..

i checked the cilinderhead numbers on the intake runners :  3870277 and close to it there is the word "truck"   

So the heads are truckheads i asume....

And the intake has this number : 4173915  2   ( casting date 4-11-80 and the letters BZC )

can't find it anywhere

I have no listing between 37xxxxx in 75 - 40xxxxxx in 80
you spark plug problem also has me baffled , you shoul dbe using a N series plug , but the plug you have in there looks more like a J series , the plug threads should be 3/4 of an inch long not short like yours are so you either have a unique set of heads OR you have the wrong plugs installed in those heads
