Header for big block swap
#2
#4
I am running a 557 with alloy heads too.
The pipes are 1.55" x 2.25" at the head.
1.875 pipes into 3" collectors.
They were the best off the shelf solution I came across after months of searching and trying 2 other sets. I am not able to legally run the fenderwell exit pipes over here like Mad dogs or L & L's.
I have taken care when porting the exhaust ports to keep them matched to the headers though.
Cheers

Below is a quote from a customer review posted on Summit which put me onto the port size, though he used an uncoated set for a Galaxie fitment they are the same at the head face.
"I will start by saying that these WILL fit a 1968 ford galaxie or XL (if you made your own mounts and have the engine setting back a bit)....therefore they should fit 65-68 as they have the same frame. So, if you swap a 429 for the 390 these work great! These also have the CJ port opening, as the product doesn't really state that. Pros...Full length and CJ openings...Larger diameter primaries. Comes with all the hardware to install. Fit a galaxie that has had the engine swapped to the 385 series "
