    Looking for a set a headers to go on my 454. Does anyone now which ones fit best and do not cause any clearance issues such as hitting the leak spring shackle bolts? Also what would be the best gasket to go with to solve leakage issues?

    Doug's or Doug Thorley Headers are some of the best on the market. Also as far as gaskets go with copper or aluminum.

    I run Hedman on my 454. Seem fine, no clearance issues. I use copper gaskets.

    Do you have a lift on your blazer? I have 5" of lift. 4" suspension and 1 " body. I emailed headman and they say they would'nt now if there would be any clearance issues with a lift or in a blazer since they don't design any for this application.

    Doug Thorleys fit great but they have the crappy 2.5" collector which should be fine on a stock 454.

    I think I might try some Hookers on my K30. Have then in box and will be installing them soon. Read good things about fitment here.
