Professor, to confirm, the hedman 78500 shorties will not fit an early A? I have a 63 A 360 with EQ iron heads (I understand the ex port is a bit different). I have a set of those hedmans not yet installed. I mocked up some magnum ex manifolds but I had to jack up the eng to clear the steering box to where I dont think the air cleaner will clear the hood plus I also had to lower the steering box. this is a hobby stock race car with thin aftermarket steering column so there was no interference there. is there another set of iron ex manifolds that flow reasonably well? Professor thank you for your thoughts. RR
