I am looking for a set of headers for my 70 Impala , I found this site by looking at reviews for Sanderson Headers, and dont think i want them based on more bad reviews than good,. I have a set of DYNOMAX ceramic headers 0n the car now and I am not happy with them because of the spark plug clearence, it is almost impossible to get the boots on let alone chang a plug, on about half the plugs . Can someone research this and HELP me select a medium range and priced header to fit this car? thank you Mark
