INFO for anyone doing this stock heads for AFR swap.
You will have to dent both, the #3 and #6 header tubes to get the standard length spark plugs on cylinders #4 and #8 to clear on angle plug AFR's.
Accel doesn't offer 14mm x 3/4 depth, w/ gasket/washer, header sparkplugs for this application.
Oh and with my passenger side, I will have to pull the header off to get the plug out after it's in and you also have to use the thermal plug wire protectors.
I'm starting to hate my car and my back hurts... (poor me)

 

Interesting ... What AFR heads do you have?

 

Now which AFR angle plug heads did you get? Their standard angle plug or did you order the L98 angle plug version?

 

Damn, glad I have the straight plugs.

 

Not sure, I've never seen the L98 Angle plugs to know. These go in at an angle and the outside ceramic piece points downward while angling in.
I wish I had straight plugs.

 

From what the sales guy said on the phone when I ordered my AFR 195 heads... If you run a straight plug head you're limited to using the 1" 5/8 headers. I got the straight plug version and probably can always come up with something in the future if I decide to go bigger.
