Small block headers: worst to best fitting. List your experience.

I used to run Hedman and hooker, then I switched to tti step headers.
With the exception of having to put a thick washer under each motor mount, solid motor mounts are what I use, the only real complaint is that with a 4-speed you have to cut the arm on your z-bar and move it over a little bit.. that and the fact that trying to put a clip on that clutch fork rod is damn near impossible once it's all in the car and bolted down.

All required the centerlink moved to install ..
Withoutna washer under the mounts, the idler scrubs the pass side header, hed/hook.
Hedmans n hookers hang the lowest on the driver's side..and end up 1st to hit dips and tracks..flat spots.
Hedman usually needs some hammering to clear power steering in a couple spots.
Tti needs z bar modified and washers if to clear power steering set up and center link even..

TTI's to 3" and a well built small block with good heads and .500 + lift/280*+ camshaft is the ticker between those 3.
