[DeTomaso] Header Gaskets & Bolts

[jderyke at aol.com]

FWIW, I use grade 8 allen head setscrews and nuts. Tightening and loosening threads in aluminum heads doesn't typically last very long. And if you need more clearance, make more clearance with a hammer and punch. An episode on Engine Masters showed that minor or even major dents in headers does not decrease power from an engine.J DeRyke

  Thanks Mike, that's what I had on the old engine, just concerned about
  not using locking bolts. I have had to retighten a few header bolts in
  the past with a brand of gaskets I don't remember.

    Richard,

  I'm a huge fan of the Remflex gaskets.

  As for header bolts I am a HUGE fan of the ARP small-head bolts. These
  are standard 3/8 bolts but they use a smaller 5/16 wrench for vastly
  improved wrench access. They look weird and work great.

    Anyone have recommendations for the best header gaskets and bolts?
    I've got CHI 4V heads and Ansa GTS exhaust system.
    I've found the top rated gaskets to be Percy's (XX Carbon and Seal
  For
    Good) and Remflex.  The top bolts appear to be Stage 8, Mr. Gasket
    Headlocks, and ARP (non-locking).  I want the best setup to avoid
  leaks
    because I'm going to run a Sniper EFI and as you all know, O2 sensors
    don't like exhaust leaks.
