I do not have those specific headers but I have ceramic coated block huggers. I love the ceramic coating but be careful, I thought I had a bargain but ended up with spark plug clearance issues. I had to use the time worn method of denting the headers which ruins the ceramic.
Hopefully someone with experience with those particular headers is in here.

I have Dynomax on my 76 & been pleased with them for the price. Very easy install. Plug acces is ok. Been on the car for about 2 years & still look good, finish has dulled out somewhat but still look good.

I've had very good fitment with Dynomax on several different models of Chevrolet-including my Vette. I have a set of Summit(Flowtech) on my 1970 Monte Carlo. With the stock heads, they fit ok, but with aftermarket aluminum heads, the fit is terrible.

I have FlowTech's on my 76.
Good fit and nice header for the money.
Mine have been installed for a little less than a year. No spark plug clearance issues on stock heads other than having to use a wrench on a few for installation.
However, I have switched to aluminum heads lately and clearance is now an issue.
I had to do like many others and dimple, wrap and then sleeve the wires
.
Also, try to keep in mind, ceramic headers WILL rust, as you can see in the pic above.

I have them on my 75 also with ZZ4 engine and Al heads, full length headers. Perfect fit, have also noticed that the cabin was cooler due to reduced under hood temps from the ceramic. Flanges are slightly heaver than the Dynomax I'm told.
