well I thought I lost my opportunity to flow test my buddies Indy heads but he dropped it off Thursday for my son to put on his engine. He called me over the weekend and said he would pay me to flow the unmodified 345 cnc’d head. Well after Church today I spent hours flowing not only that head but also the one that was leaking water in an exhaust port and unsuccessfully I tried to have it welded. I also did some air speed testing. I will post the numbers tomorrow but here are some pictures.
