Re: what type of plugs
I've always used std length plugs with my headers, and have never had an issue. i guess it really depends on which headers you are running, as some are bent more aggressively (for lack of a better word) than others.
I've found that a good wire loom is a necessity to keep the wires where you want them. as far as brand, i used bosch for years, but have recently gone back to NGK's using the reasoning: #1 They're cheaper #2 If They're good enough to be used by GM at the factory, they're good enough for me. ![]()

Re: what type of plugs
the accel header plugs will probably be your best bet if the clearance is really tight, while your at it get a set of quality wires. taylor msd moroso etc. stay away from accel wires as they tend to leak a lot of voltage causing misfires and a pretty lightshow under the hood.i always reccomend taylor wires personally the boots hold up to heat very well on the plug side and they last a ton longer than any factory wire and also have a lot less resistance in the wire itself

Re: what type of plugs
Taylor all the way!!They make 1/2 the other wires out there anyway.Taylor "IS" wires.I`ve never had headers bend into the path of the plug.The socket may be tight against them and sometimes I`ve busted a plug from that.But either way the socket`s going to be the clearance issue,not the plug.I`d go with any "quality" plug with a higher heat range for the HEI.

Re: what type of plugs
^what's the part number on the wires you used?
I just ordered a set for my silverado. The 67 could use a new set too.
