2g head on a 1g???? Options

[AWD DSM 1]

Don't ask me how, but somehow the head that I had rebuilt turned out to be a 2g head. I didn't even realize it until someone else pointed it out to me. My question - is this gonna cause problems? Will the CAS bolt up ok? I niticed how dramatically smaller the ports are, if I port them out will that be just as good as a 1g? Or should I be selling this head and looking for a good 1g head to put on? Will the ARP stud kit I have coming work with this head? Please somebody tell me that I'm not totaly f#$%ed....

And the saga continues...

Anyone know offhand where I can find casting numbers on the block and head to find out what exactly is up with this motor? I sold the head to Rob after pulling it out of my '90 GSX. I'd assumed that everything was stock as it was an unmodified car. I'm wondering if someone dropped a cheap 7 bolt in at some point in its life now after I hear this from Rob. I really don't want to sell extra parts from it and disappoint another buyer. That and this little mystery is really bothering me. I honestly doubt either of the two previous owners would have had the know-how to even put on a head much less do a 7 bolt swap so I wonder if a shop located a cheap one at some point in the car's life.

Anyways if someone can tell me how I can shed some light on this I'd appreciate it. Sounds like more informed sources than I are pretty much sure that it IS a 2G head.

Sorry Rob didn't mean to add to your headache here. I'll do what I can to make things right.
