The FI engines have a tapped temp sensor boss near the #4 spark plug. 
Type 3 engines also do NOT have the dowel between the intake ports 
that dual port Beetle engines have.

'72-3 Type 3 FI engines also came with breather ports into the rocker 
boxes, near the #3 &2 spark plugs. I don't think Beetle engines ever 
got those breathers. Those heads are hard to find.

If your GEX engine is carbed, it most likely has either beetle heads 
or 68-71 Type 3 FI heads, but nothing is certain until you look at 
them and see what features they have. The VW part # (if they are VW 
parts) doesn't tell you anything, because that's just the casting 
number, and VW could have made any head from that casting.
