whose dealt with these type of headers and are they worth it. would you recommend them?
what is the difference or is it just a name?

 

Some of the best headers made, I like them better than Stainless works or Kooks.

 

Iv'e heard plug access is not that great. Take it for what it's worth. MachinistOne, what's your opinion?

 

I should have specified that as a blanket statement, I have used them in many applications and was very impressed with them(build quality), but not specifically on a f-body. So as for plug access on this car I don't know.

 

I believe Dynatech made FLP headers. The FLPs where known for having terrible plug access on a few of the plugs. I think I remember reading that the plug boot was almost impossible to get on, because the primary was so close to the plug. They do have pretty good ground clearance goes though.
