Cutting Excess Guide from ProComp 210 SBC Head, custom Porting Combustion Chambers 4
Part Four of Port modificatins on ProComp 210cc aluminum SBC heads. Guide over hang from installation and correcting the combustion chambers to unshroud the spark plug is a big deal on these heads. China castings leave a lot to be desired, but still with all the work you must do it is still the bargin of the year and is a force to be reckond with when "bang per buck" is needed. The base of the spark plug should not be exposed in the chamber, and any valve guide "Overhang" will obstruck flow and create fuel "sheer" which seperates vapor to droplets that wont burn. Most Big Name companies will not take time to detial these issues as production cost prohibit these mods, so have your local machine shop take apart your heads and look for these problems before you bolt them on your prize engine. www.headbytes.com 615-212-7168





Porting Pro Comp Chambers for airflow unshrouding
PLEASE READ; This envolves porting the combustion chamber floors to line up with the 30 degree final seat in the bowl. The chamber is full of humps and machinist ridges where the aluminum is "overhanging" the hardend seat, along with PRO COMP making the spark plug hole too long and you have to cut the chamber down level to the spark plug surface with the plug in the head.
