i know its been discussed a few times before on here, but just wondering the difference between the 1/2/3 gen heads for an EA82T other than just the composition of the metal???
what brought up the question is that i noticed the metal oil line from the head going in/out of the turbo is different between 1st and 2nd gen
my 87 GL Turbo has 2nd gen heads w/235,000 miles and 87 RX Turbo has 1st gen heads w/245,000 miles
1st has ea82 with no marks
2nd has ea82 underlined
3rd has ea82 boxed in
