    went to put in the sparkplugs on my rebuilt 350 and one side went fine but the other side i could barely start the plugs and when i did it didn't feel right tighting them. whats a good way to clean them out, they look a little dirty.

    i'll do that,how much do they run for? will checkers have it? will it help with rust? they look all surface rusted. i tried some wd40 and slowly screwin the spark plug in and out, it helped alot but one still feels boogered up.it gets tight before it bottoms out. could this cause the spark plugs to sieze in the threads after use? :mad:

    Make sure to put some hi-temp anti-seize on them when you install them and it should keep you from having future problems with them sticking in the head. :D

    chasing the treads...

    You need a thread chaser as suggested already..I'd use never-seize on the plug threads,but be sure not to get any on the porcelain or the electrodes--it will conduct the spark and ground out the plug,and cause a "dead" cylinder..!.. :crazy:
