The Accel "shorty" header plugs are the shortest I have found.
But in your case, I don't think those will even help.

Re: Running spark plug wire without boot?
Upon doing some research I discovered that shorty plugs exist. I ordered a set of the shortest shorty plugs from Summit so we'll see tomorrow if that works. Also I ordered some plug wraps for further insulation, hoping that doesn't just amplify the clearance issue I am having.
Also, prior to reading the comment about arcing, I tried out running the plug without a boot and sure enough it was just arcing off the wrapped header bad enough to not even fire the cylinder... hopefully it didn't hurt my brand new engine

Re: Running spark plug wire without boot?
I had a similar situation with my RHS heads and SLP headers. #8 cylinder. Burned through the first boot which actually touched the header. Put on another boot, but trimmed it down so it wouldn't physically touch. The boot stayed together, but still burned, and started arcing. Now I'm running a DEI wire protector, and no arcing. The wire sleave/protector is DEFINITELY touching the header, but between that and a new, trimmed boot, I have no arcing.
...I'm also running Remflex header gaskets, which are about a 16th of an inch thicker once compressed. That's a lot of real estate in these situations.

I'm also running Doug's long tube headers, with aftermarket aluminum straight plug heads and what I did was run the thick aluminum header gaskets and slightly dented the #7's primary tube right where the boot sits; all this gave me a good .250" of space between the boot and header, running Champion 792 racing spark plugs.

I've also got PN# HMI-8030 spark plug boot insulators. Have yet to use them but from the feel of them they are extremely sturdy and seem like they should last forever.

Re: Running spark plug wire without boot?
You could always buy a header flange to use as a spacer and use gaskets on both sides.

Re: Running spark plug wire without boot?
running shorty Accel spark plugs has given me enough clearance to put the plug boot on as well as the thick plug boot protector from Summit. The protector touches the header quite firmly but I think they are quality enough to not disintegrate from heat. Also my headers are wrapped so I'm sure they'll be fine. Thanks for the help TGO!
