Has anyone tried using an additional exhaust manifold header flange to gain spark plug clearance?

What heads and headers are you running Larry ? I'm running Doug's D452 headers and Indy EZ's with Firecore wires and zero issues. Gus

What heads and headers are you running Larry ? I'm running Doug's D452 headers and Indy EZ's with Firecore wires and zero issues. Gus Running RPM heads with older style Hooker tuned headers. Current number is 5209. I wasted money purchasing the Accel shorty plugs. They are less than 3/16" shorter. Didn't help at all!!! These headers have separate flanges. I actually have to loosen the #7& #8 flanges to get to the plugs. I wanted to go with the Doug's but they are not a tuned header! TTI was also an option, but I would have had to buy a $300 starter, plus the $700+ for the headers to make them work. Too much $ for my blood. Got what I thought was a good price on a nice set of coated Hookers, but now have issues. May put my old CPPA's back on, even though they aren't a tuned header.

Do TTI headers need a specific mini starter or can you use a Dakota 318 2 wheel drive starter? That's the starter I run. It's the size of a mini and costs $80ish The 2" tube and larger TTI's need a special starter due to clearance issues. The 1 7/8" and smaller do not. The stock MOPAR mini will work. Mind you, I'm talking a manual transmission with a 143T flywheel. Automatic transmissions are another story....
