After mkt headers spf?

[tortuga]

Anyone running after market headers on a superformance?

I have headers from Gas-N on my 289. I am not sure if Georgie makes any for a Mark III.

I ran the headers from Ron Roberts (RIP) Firefly Performance. Good kit. A friend has these now and will be using them in his SPF 427W along with Ron's sidepipes.

I designed header flanges and the 8-bolt square flanges these were laser cut by a local shop (Grand Rapids, MI).

A new set of headers was built locally. We followed the design concepts of Ron's headers and then mated to Ron's sidepipes for my FFR Challenge Car.

Georgie does a couple of header versions for the MK III and we have customers using them with great results.

I have Georgie’s SPF MKIII headers. They are nice.

Ron Roberts (RIP) Firefly is a good kit

I have Georgie’s MKIII headers. They didn’t fit quite right, but Georgie got in it and made another one. Excellent customer service.
