Ive been researching headers as well. Headman is looked down upon but Hooker are said to be good. Thats all I can say for sure though as I havent researched the sizes and other material.
Edit: Theres a saying of you get what you pay for. Pay for junk and thats what you usually get. Not always but 8 out of 10 times yes. Research some and find out what you need then go ahead from there. You can try to sell your headmans on Ebay but I wouldn't get hopes high for regaining what you payed for them.

Nothing at all wrong with Hedmans. They make different models of headers and the tube thickness differs depending on the model.
The Hedman Elites have the thickest tubes and the largest flanges. The ceramic coating helps to keep them from rusting and control heat.
Hedmans are not "tuned" (equal length runners) like the Hooker Super Comps but they don't cost as much as Super Comps either.

TPiS will fit just fine.
Now, if you want everything perfect, youre out of luck. TPiS headers will rub the plug boots, but if you put socks over them, the plug wires will last quite some time.

Are you making 600 or more HP? That'd be the only reason I could possibly imagine that you'd think you might need primaries that large.

Sounds like you've got headers made for something else. And I also agree with Corvette Kid; you need to have a very highly modified motor to need that big a header pipe.

Same here. No problems at all. Why, in Gods name, do you want 1 7/8 on an 85? If you have modded that L98 to the point 1 7/8 are required header fit should be the least of your worries.

Hi. I have an 85 Z-51. Bought TPIS headers and they were easy to fit and even all the stock accessories could be fitted without difficulty. The only thing I had to do was change one bolt to torx or hex and to gring or file half a mm off the alternator support. They fit fine without doing anything to starter . I put in a heated O2 sensor because the stock got into closed loop much later than with stock manifolds. That is ofcourse not TPIS specific but headers specific. Great performance increase. I had coated headers and that I recommend to decrease the heat from them and also rust. HAve had them for four years now and no problems. I live in Norway and great service from TPIS and fast delivery.
have not really any problems with spark plugs. I have 90 degree boots on the sparkplug wires and wires that manage high temp . Till now No problem with changing sparkplugs and wires to them
Good luck
