Cody,I am impressed,you measured.If you are running a 4 inch spacer,(hood scoop?) Might be in your best interests.Do the comp test/ leakdown check.If even, the recommended carb,basic 750 double pumped,out of the box.If that doesn't E.T.quicker,I would consider an M1.Same boat as you,dude.Pulled the heads,to port today,good luck.
