Yes you can. There's 4 variations on the Cleveland head, first is the 4V head (D0AE-H, -R) with closed wedge chambers (62.8cc) and huge ports (2.38 x 1.63 intake and 2.00 x 1.46 exhaust). Then is the 2V head with smaller ports and open chambers. Third is the 4V open chamber head (D1ZE-DA and D1ZE-GA). Finally is the Australian head that has the best of both- a closed chamber with 2V ports for improved low end torque for the street. Don't look for a domestic part number for the Aussie head. Look for the smaller ports and closed chambers.
The 4V closed chamber head (61.3 to 64.3 cc) yields 11:1 compression when used with stock pistons while the 2V head open chamber (74.7 to 77.7 cc) yields 9.5:1 with stock pistons. The 4V head has the same port size as the Boss 302 head while the 2V is considerably smaller. Overall, all 4V heads, including Boss, High Output, and Cobra Jet, all had the same port sizes. If you want good low end torque, go with 2V heads. For higher horsepower, go with the 4V head.
