heads for 73 1700 CC engine

old heads (one dropped a seat):
021 101 371 Q (air injection ports for exhaust)

new heads (bought off net)
022 101 372 3 (no air injection ports)

looks like everything will bolt up no problem,

are these the correct heads for 1700 73 bus?

should I replace both with the "new" ones I
bought, or just left side, which dropped
the seat? I read you should "match cc's",
IE make sure both heads have same volume.

Everything you ever would want to know about type 4 heads.

If I read it correctly the new ones are 1800s--to big.
Hard to make them smaller for your 1700.
Measure the diameter of the combustion chamber to see if they are equal.
The 3 in (022 101 371 3) probably an S.

I do have some 1700 heads and could trade you for your newly acquired
1800s--are yours used, rebuilt,or new? I would only do this if your 73 bus
was dual carbbed and not FI--larger valves 41mm X 334mm.

I have not looked @ my shelved 1700s for awhile so I can't remember what
shape they are in. If your interested I will look closer @ them.

An option is to find old 2000 crank rods and PC kit from 79 bus or 80-83
Vanagon on e-bay or samba and build a 2000 for your bus. You can use your
case and newly required heads. IT will kick

This is what I did in your exact situation.
Another option is to find bad engine from 80-83 Vanagon @ a bone yard to get
these parts. Many of them also have seats dropped and can be had cheep <
$100. The Vanagon has a different type head, but you have new heads to use
so you don't need to worry about this. Make sure you get all L-Jet FI
stuff if you do this--it is much better than carbs.
