Bolted up ok, but could not use the plugs supplied where the a/c mounts had to use socket head plugs and do a little grinding to get everything to work

Comes with gaskets and lower bolts.The bolt holes on the outside were not machined. I needed to die grind before using.

Installed on a small block Corvette, could not get it to mount. after many on, off attempts finally noticed the casting was way off on one of the bolt holes not allowing the bolt to go in straight... of course the one hardest to see close to the firewall I was able to grind it out to make it work, but a lot of time and effort when a few bucks more up front would have been worthwhile.

The price was good on these but the quality when I received them was disappointing. I had to use different gaskets other than the ones supplied as the manifolds leaked with the gaskets sent with the manifolds.

One of the boxes was missing the bolts for the smog control. I will send an email to Dorman to see if they can ship them to me. Other than that the manifolds are what I expected.

I used these on my 1981 corvette. The manifolds from the factory had the AIR emission system with a smog pump and EGR valve. I removed all of this so the engine could breathe better. Easy installation, came with the hardware needed, great price. The factory manifolds were junk.
