Just a 'heads-up' on close fitting headers. I pick up a nice set for my 350 install from a buddy for a really good price only to find the spark plug boots touched the headers on several plugs. Returned the headers to my friend and paid big bucks for another manufacturer (Sanderson). On the way out the door the salsperson told me to be sure and install short sparkplugs or the boots will touch. Huh?! Are not all car engine spark plugs about the same length? I had already purchased and installed a set of AC Delco plugs as it's a new GM 350. Bought a set of correct heat range NGKs...problem solved. That brain poot cost me a $175.00.
