I agree, Vortecs and a mild cam would probably be a great solution. It really depends on the current pistons, the Vortecs have a 64cc chamber so it's easy to get too much compression with no-dish flat tops made for 76cc chambers.

It would be nice if it's a roller cam compatible block. Google images can help with the ID, it's pretty easy to see the difference with side by side pics. Easy enough that you can tell by looking thru the head casting holes with just a valve cover off.
