    Rated 5 out of 5 by from Good to go I had heads flow tested before installation and found to be 8 to 10cfm average lower than advertised. However I had 5 angle valve job and the bowls polished and gained average 35 to 40cfm increase. The cylinder head shop was very impressed as well with these. They have received other brand name heads 30cfm lower than advertised, which was good to know.
