ITS extremely important that you ask questions and get accurate answers , BEFORE purchasing headers about what style cylinder heads the headers are designed to fit, below is pictured a set of headers obviously designed for factory strait plug heads but bolted to a set of angle plug heads making spark plug access and wiring a clearance and heat , destroying ignition wire nightmare
angle plug
if you got so much mileage from the last set that you can,t even remember when you bought or installed them Id sure pull one and buy the same ones again, as they obviously last a good long while!
please post pictures once they are out, as clear picture can tell you a good deal about condition of an engine and combustion
(don,t forget anti-seize on the new plug threads, and if the current plugs won,t back out easily try spraying them with a good penetrating oil spray, a couple times and letting the engine sit for a few hours, to soak the threads spray again every 30-60 minutes with a good penetrating oil spray,while you wait as you remember, too to allow the oil to loosen the threads you sure don,t need stripped plug threads, by forcing them. )
before RE-INSTALLING,
COAT THE SPARK PLUG THREADS,
WITH ANTI-SEIZE PASTE,
as it tends to prevent future problems

plug fouling, issues
hi, Im wondering if an auto spark plug can burn carbon off once it is all carboned up if the changes are made to the engine to give the proper air fuel mix. Can plugs be cleaned of carbon and can plugs be bead blasted to clean or does it ruin the plug. What would be a way to clean the plug? Or...
