About a month back I purchased a used one of these for practically nothing. Problem is, no fuel bypass pipe (already got), and no hardware. The hardware is the issue, from what I gather using the install PDF provided by Ford I need: x2 M6x110 Long bolts (Center Intake Bolts) x2 M6x50 (Front Intake Bolts) x6 M6x35 (Remaining Intake Bolts) x4 M6x25 (Throttle Body) Originally these came with head cap bolts which I find meh...So my question is could I go flange on these instead? It would beat me having to use any washers, or is there some sort of reason behind Fords decision for using Head Caps? Thanks in regard.
