1957 headers

I probably put the cart before the expensive horse but here goes--have heard mixed results about differing headers on a 57 with FE. ran across post on 57 forum that hookers for 63/64 would work fine--having hard time getting back on the forum so thought I would throw it out here. The coated hookers I bought look really good but my initial feeling is AINT NO WAY THEY ARE GOING ON!!--i have a 61 that they can grace but thats another story--anyone put some 63 hookers on a 57?? if so what did you have to tweak?? I get differing opinions on FPA about ready to find a custom builder to get this done. everyone chime in cause I only have 6 hammers and dont think any are big enough!!thanks--have a great christmas and a 2009 that curves upward!
