After paying over $1400.   canadian for a set of hooker headers from summit for a 69 fairlane with a fe. We waited for more than a month and a half the box finally arrived here in northern ontario.  We opened up the hooker box and found a scrap 69 fairlane fe header.  The tubes stuck out a quarter inch past the mounting flange.  For the drivers  side they actually sent a shorty header for some type of small block chev. 
    Called summit to return at our cost then almost two months later another box show up from summit.  They sent the exact same headers that were no good the first time right down to even the same shorty header.After sending the box back again... four and a half months later the real set showed up.

Hi guys awsome forum it is nice to see and hear of other fe fans.  But I couldn't help but notice not many people use the shelby Mr head.  Is it just due to cost or is there other major problems to make others better? Would there be that much of a loss in power on a street car under .600 lift in comparison to tfs heads.  A friend just put a set on an old 427 block with a 4 inch stroker crank.  A bad intake choice really killed power, the port matched performer rpm couldn't flow enough.  It made good power and torque form 3 grand up but stopped off at only 526 at 5800.  Engine builder dyno operator suggested a victor junior would be worth 50hp plus. The motor produced more peak torque than horsepower.  Has there been many out there with shelby head expirence out there?
