Lightbulb Chevy LS cylinder head bolt pattern needed

Hello everybody
I need someone help to make a bolt pattern from the chevy LS engines ( LS1 or LS3, I guess they all use the same pattern).
I'm from Brazil and wondering if it's possible to make a hybrid cylinder head to chevy inline six (235, 250 and 292) using a pair or the LS heads. Leo Santucci made just that, (http://www.crankshaftcoalition.com/w...evy_250_engine) but he used SBC heads with the 454 bolt pattern, that one with 5 bolt for each cylinder.
The chevy LS uses 4 bolts for each cylinder just like the chevy inline six.
I've got one 292 engine that I'm building to power my 82 chevrolet Veraneio (Brazilian model just like the 80's suburban).
Here in Brazil v8 powered cars are little used and v8 engines are quite expensive in all ways you can imagine. (Here a brand new Camaro SS cost almost $100.000. That's right, 100.000)
Thank you for the help!

I downloaded an LS3 CADD file from GrabCAD a while back, no guarantee this is correct.

Does anyone have the print of the bolt holes on the front face of the passenger side head?
