Can you claim a 1967 belvedere as a gtx to use the 440? Also, this motor uses the 915 ( closed chamber) head. But the engine specs guide offer the 906 ( open chamber) head to be used also. Would you shave the 906 head to make it a closed chamber head? Or is there a different way to go about this? Thanks in advance for any explanation, I really don't know who else to ask about this stuff.
