1g and 2g head difference

[yoder]

ok havent found nothing really on what im looking for i have seen a few thing that kinda help out but i still cant really tell how to determine the difference between a 1g head and 2g head i have seen the answers like bigger ports on 2g and bigger TB on a 1g but i got the car and its a 2g 7bolt block but cant really tell about the head though if its a 1g or 2g some help would really be great cause i would like to just get a new head gasket and transfer it over to my 6 bolt block that i have rebuilt

Look on the front of the head there should be a little square looks like it Dosent belong. There should be a dot on it, one for or hole thing is a 1g. Two dots are for a 2g head .

Honestly it should be easier than that. A 1g head would have a 1g intake. 2g could have either an evo 3/rsr or 2g intake (unless aftermarket). The intake manifolds arent really interchangeable.

Right side right above the exhaust manifold.

Close. It's the location of the "dot" on that flat, not the number of them. See: How to distinguish 7 bolt head, 6 bolt non-turbo head, & 6 bolt turbo head

Actually, the dot trick is about as easy at it gets. A 2G head can use a 1G intake manifold but it will be very suboptimal. The reverse is not possible -- a 2G intake manifold cannot be used on a 1G head because it won't seal: intake manifold difference

I suppose but I dont think the car would run anywhere close to right with a bit flat surface for air to smack into there. With as cheap as parts are I dont see any reason why someone wouldnt install the right one (of course I know people still do dumb things anyways).
