![]() ![]() ![]() ![]() ![]() I don't want to sound like I'm making things difficult, but assuming the heads ARE to GM specs along with the rest of it without verifying is taking a gamble. Usually things result in less than spec compression etc when assuming the parts are as GM literature indicates. I would just hate to see you leave some performance in the table. |
