Spark plug gap

Thanks for the replies. Im running my timing at 34 total. 750 holley 80 in the front 85 in the back. It doesnt seem to be leaning out. Doesnt pop or anything, just falls flat on its face. I have new valve springs on the W2 heads to match the cam. It fell flat at the same rpm with the 587 heads also, so must be the cam. Just wasnt sure if the plugs and plug gap were proper for this setup.
