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

-
Going to be ordering some by august/september. Will post what I get. Appreciate all those that took the time to post their experiences with these type of parts.
 
Are small block Edelbrock Performer heads wider than stock heads? Because Doug D453s with performer heads and a Borgeson box definitely don't bolt in place without beating on them with a BFH.

I tried using the thicker motor mounts and while they help, they only cause you to have to beat clearance into the headers a little less. But these motor mounts also cause problems such as your distributor plug wires hitting the bottom of the wiper motor and the pinion angle getting out of whack.

I'm currently working on getting them working with stock mounts and home made 1/8" motor mount shims.

I don’t think so? Are you centered properly in the engine bay?

I do know that tti’s and an early version of the borgeson also did not get along too.

If anything I'm aligned a little more toward the passenger side. I bought the Borgeson box last year so it's gotta be the newer version. This is also a magnum block, if that makes any difference.

I run a magnum and tti’s on a stock pwr steer box and it’s good. People say Doug’s also fit my application good to. If the motor is centered right and high enough I’d have to say it’s the borgeson?

I did have to grind down the mid truck mount bosses (both sides) on the block for the tti’s to rest flat against my head. Are yours clearing there?

See the chart in post 58. Your whole engine should be 1.25" closer to the passenger side of the car as well. Verify all of these measurements to eliminate misplacement as a potential reason for your clearancing woes.
 
spitfire/laysons tri-y shorty headers, very happy. Lots of minor work to make them fit right. Great plug access, starter not trapped, heavy gauge tubes. Quite a power improvement over 65 Barracuda 273 manifolds
 
Has anyone installed Sanderson's DD9 Originals?
They are out of Northern California; I have seen them on a bunch of guys cars in Northern CA.

I got some hooker super comp 1 7/8 slip tube under chassis race headers 3.5 inch collectors with O2 bungs and no flanges...also have the extentions to tune them 8 long ones 8 short ones....also have some headman hustlers slip tube under chassis headers 1 3/4 with stainless merge collectors ....both are for 67-76 abody smallblock.....also have some ceramacoated JR's fenderwell big block abody headers 2" missing collectors..really cool and vintage....all for sale...but shipping would be astronomical....

I had a set of headers shipped to me for under 70 bucks.

I used Pirate Ship. It’s much cheaper.
 
worst fitting is any of the hang low bullshit headers. hooker (competition), headman,flow tech, summit....etc..etc...etc

best fitting are tti and dougs.
 
I had no issues with hedman. They weren’t easy but no use of a hammer and fit with power steering. Yes they hang in driver side. But never touch the ground. Not as good as Doug’s but I got them brand new for $100.
 
good to know. pirate shipping is cheap, but if your buying from a manufacture, they probably already get cheap shipping or won't use them. might have to splurge for painted Doug's as ceramic/thermal coating is like $300 extra.
