300 I6 Headers
Hey folks, wanted to start a(nother) thread on exhaust options.
I know it seems like a lot of guys run the OEM EFI manifolds and the walker Y-pipe. All those parts new would be around $150-180 from what I've seen.
Hedman makes a long-tube in steel that comes with non-high temp temporary paint that runs about $250: https://www.summitracing.com/parts/hed-89300/make/ford
Hedman also makes what appears to be the same header with ceramic coating that runs about $550: https://www.summitracing.com/parts/hed-89306/make/ford
Clifford Performance makes one that is around $460: https://cliffordperformance.net/stor...-truck-headers
I recently came across this header for $272 (on sale, regular shows as $485): https://www.protuninglab.com/hds-fpu...SABEgKBvfD_BwE
Doe anyone have experience with this company and especially this header in particular? It shows to be stainless steel, which I have always heard is better than painted steel and exterior ceramic coated (though probably about the same as a high quality fully ceramic coated header). For $272, it looks like a heckuva deal.
What are y'alls thoughts? I might go ahead and ****** one up for the 1983 F-100 that I am planning to rebuild throughout this year.

I run the EFI manifolds with the water heat plate and no problem with how it runs.

The current plan is to run a 268 Comp Cam. The 4-barrel Offy intake. Heads and shortblock rebuilt. Stockish compression, maybe a slight bump with milled heads.
And a Holley Sniper 2300 EFI kit. With timing control and a stock, locked out distributor.

I run a set of the Clifford headers. 15 years with no leaks or thru-rust. Any set of long tubes will require a custom y-pipe of some sort.
The reason for the efi manifolds being so popular is they can be bolted on by anyone and there is a prefabricated y-pipe available. The efi manifolds flow very well for a factory manifold. They wont scavenge quite like a long tube header, but most 300s dont need that per say. They also dont cause starter access problems and they dont radiate heat like tubular headers.
The factory cam has an equal duration as the comp 268 cam. May I ask why you chose that versus something peppier like the Schneider 135H or 140H, or Erson E270321? The comp 268 can basically be mimicked with 1.73 rockers on the factory cam.
Here's a list of all cams available for the 240/300 inline six block.

The Holley sniper 2bbl efi system is a good choice for the 300. I know one 300 running the erson cam I mentioned, the 2bbl Sniper efi, 9:1 compression, and efi manifolds. It's a healthy engine.
