    20972 is rated 4.7 out of 5 by 7.
    Rated 3 out of 5 by from Problems This will not work on 454 bbc. Exhaust rocker studs come up too far into poly lock. Leaves no room for set screw to start thread. Poly lock is too short. These measure 1.110”. Actual. You will need the 1.200” poly locks from Scorpion. Until Jegs does their research don’t buy them. Summit doesn’t know either.
