Cyclone Headers

[Roybetty]

Hi there,

need some help for my old K10. I have some Cyclone performance Headers for my 5,7 sb engine but it seems they didn't work well. On driver side the header touch the engine mount a bit and it also seams the transmission steel frame is in the way for the following hose. On passenger side it is very close to the shackle.

What is the best header for a 1976 Chevy K10?

Maybe someone know the correct name of the Header I have?
It seams to be an old one from arround 70/80 Called Cyclone Header.
There is a plate on it with following text: Cyclone engineered by Bob "H" or "M" could be also "Mc", then double "dd" and "en" and then serial 56660) I can't read the signature of Bobs full name.

Sorry for bad english and thanky for any help!
