FE Technical Forum / My C0AE-D head journey
« on: October 29, 2020, 12:47:58 AM »
These cylinder heads seem to follow me around. I've never really perused them but I think they're cool and pick them up when I find them for a reasonable price. I ran a pair of them once long ago and got fair performance from them. I've never seen hard data on them so I was excited to see that Brent was going to try some on Junky Junk. When he decided to not use them I had to text him and tell him that he sucked for abandoning the HiPo head. He said that in conversation with Blair Patrick that they decided that they did not flow well and further work done to his C0AE-D heads would be a waste of time and money. Fair enough.
In another conversation with my good pal Ross he suggested that the compact chamber of the "kidney bean" cylinder head was the cause of the lack of flow. This really raised the interest I had in the 60 year old cast iron. I took a pair of C0AE-"big"D cylinder heads to Tim's Porting in Santa Clarita, California. I had Tim flow test a CNC ported pair of Shelby aluminum heads with less than stellar numbers in the past, so I don't think his flow bench is a "happy" one. His shop does mostly LS and Ford 4 valve stuff and he has no particular FE experience. First was to flow the stock head. As you can plainly see Blair and Brent are correct that the flow is dismal.
