Hi all, I have a 55 210 sedan with a 350 and a 700r4 trans. I am using 3/4" forward side mounts, a unisteer power rack and pinion, and power brake M/C. I am having trouble finding headers that fit in most aspects. I bought the Sanderson 8021830 shorty headers, and I bought some Rams horn headers. The rams horn will not work because if the side mounts and the R/P. The sandersons fit okay, but even using shorty header sparkplugs, they will melt the spark plug boots. I have been looking at the williams and the dougs headers but I am not sure they will clear the R/P. Any suggestions would be appreciated. Oh yeah, I am using an Ididit column.
Pretty sure you are limited to one header that fits with a rack and I'm not sure they fit with 3/4 forward mounts. There are several threads here about header fit with a rack.
I RUN THE PATROIT 3/4 HEADERS WHICH WERE A BEAR TO INSTALL. HAD TO GO TO A MINI STARTED AND STILL DENT THE HEADER. I ALSO HAD TO TRIM THE LEFT ENGINE MOUNT
Are these the ones you are using? Part number C56 SB. https://www.sandersonheaders.com/sa...-set-for-55-57-chevy-cars.html?category_id=68
Do you have a straight plug, or angled plug?
I also have R&P on my small block 406, and had some minor difficulties with fitment (Only because I have Dart heads which are angled differently) and called Sanderson tech support. They were VERY helpful and sent me the parts I needed FREE, even though they didn't have to.
I hate to see you spend more money on another set if you don't have to...
Unisteer lists a Flowtech header on their website. Also says some gen2 Camaro headers will work.
