340 with edelbrock heads overheating

Double check ignition timing and carb jetting.
Did you degree the cam.
no , i did not degree the cam. Cam was installed by the builder. I have doubled and tripled check the ignition maybe more than that today. I have a feeling it may be running lean. I have the the primary jets at 107 and the secondary at 101 plus the rod is a .65-.037. I smell no unspeant fuel out the back of the exhaust.
