Hello

   I've run across two sets of  ECZ-G heads,  I can buy one set for $125.00
my question is this, is it worth the money for these heads even if they don't have the "post"
Reading Tims  pages, I don't think for the money spent that you can mill and resize the valves
for under $400 each in my area.
 Also reading about the casting letter (size) how would one know if you have nothing to compare with
Best
