OK, I need to buy a set of headers for my ZZ502 which I am soon to drop into my 68 Coupe. I have been looking at some shorty style as I want a low stance, but I also want reasonable ground clearance. Many of the websites/catalogs I have been looking at refer to many of the headers as "not suitable for aluminum heads". Why is this? Can anyone recommend some shorty style headers to suit the ZZ502? Looking at something more in the budget end. Any advice would be appreciated.

Call or look up Sanderson Headers,They have lots of set ups
