i'm using ngk v power plugs, they are about as short as the accel plugs everybody uses. i'm running 1 3/4 long tube hooker super comps, w/ pro action angle plug heads, and they work great. one suggestion though, the plug they reccomend is a very cold heat range, so unless your compression is up there, i.e. 12:1 plus, or are running nitrous, you'll do better with a slightly hotter plug. the plug requirements are really just a 3/4 reach, washer seat plug, pretty common really. just take the number they reccomend to a spark plug website, such as ngk, and start cross referencing. also, for reference, i'm currently running an ngk # R5671A-7 in my 11.6:1 406, w/ the 220 cc pro heads. hope that helps
