Default Headers for a 75

I'll try to get to the issue. I have a 75 4sp and I installed a BP 383 stroker. The engine is fantastic,however I believe I chose the wrong headers. I used patriot block huggers that are awesome but the straight plugs on cylinders 3,4,5,6 are just too close. Has any one with this set up used headers that were better than this? I would be quite grateful for any input you guys may have... i'm not the greatest mechanic that ever lived, but t do understand what i'm trying to accomplish and that although I probably can make this work , would be open to a change.....Thanks again for any advice.
Oh btw factory a/c passenger side.

Too close as in the headers are touching the plugs? Or so close that you think the headers will melt the plug wires?
accel does make shorty spark plugs.
other options are denting the headers slightly to improve clearance.

I have ceramic coated Doug's headers on my 75 4-spd (converting to 5-spd) car. I have good plug clearance, but my clutch z-bar is very close on driver's side.

I have the same headers as Panther-19. No problems anywhere.

If you already don't have them try 90 degree boots and Accel shorty plugs. Cheaper and easier than new headers.

I couldn't find the receipt in any of my emails, so I'll check the invoice when I get home from work. If those plug wires MelWff suggested would work, you'd be about $700 better off.
