I bought the SM heads complete.He did not have to replace anything for the selection of cam I used.Just touch up the the valve job.My Eheads will be here today and they will go to the shop on Monday.Will see what he thinks of the Eheads.His shop did all the machine work for the late great Joe Sherman.Dont have a cam picked out yet so dont know what we will do for springs.They are set up now for HFT cam and I will run a HRC.Maybe a SP II.Tom
