Supplied header bolts short
Flange is alot thicker creating a problem. The supplied 3/4" header bolts are too short. 1" bolts are needed not big deal just figure that you will need to get. Other than that the Headers are nice quality and construction.

flange height
They are very nice built headers. But if I had to change anything it would be the flange area over the water temp area on the head . They encroach on the sending unit or bushing and needed to be ground down so you can access , install or remove

GOOD FIT SO FAR
I just put these on a 1966 Chevy Impala 2 door hardtop and they fit very perfect. Originally Jegs sales person recommended me part number 555 300150 and i had to send them back because the pitman arm was hitting up against them not allowing me to turn all the way. The return process was very easy and they sent me the 300100 which I wanted from the beginning and they fit so good I'm just waiting to hear the sound once I get the motor turned over. I will be back with another review and picture of my motor once I get it running I have purchased a lot of dressing things for it from Jegs

The headers I bought.
They fit very nice. Flanges are thick and they don’t leak so far lol. So if u have problems with leaky headers like I did they are the solution. Very nice and shiny.

Great sound!
The headers bolted right up perfect. I had to adjust my exhaust but once finished the installation they look and sounded great in my 1980 Camaro, 350 SBC.
