This was a common problem with the old flat heads..I used to braze a layer of brass on top of the push rod..it dosen't take much..an extra 35 to 40 thousands of brass on the push rod will make all the difference in the world..a air leak on the suction side of the pump is another possibility..as previously mentioned.
