Was not expecting them to be this nice for the price. The welds and finish look great. They came with all gaskets and fasteners (not impressed with the cheap bolts - I upgraded those).They bolted right in to my 69 Camaro with an LQ4 LS engine, I did put a small dent in one tube for additional clearance at the power steering gearbox.

It looked like a well built product, but unfortunately Powergo motor sport Sends out someone else's returned product and will give a run around to get a return label. The box you could tell was beat up headers were loose in box beating themselves up. Bolt and gasket package were cut open bolts loose in the box. NOT SHOW QUALITY!!!! We will be advertising at car shows Powergo motorsport will be on our wall of shame borad

I guess that I didn't read the reviews before I bought these headers. It seems like everyone is having the same problem even with other plug wires than me.They look great and seem very well built but just like the rest they just cook the second plug wire on the passenger side, much too tight of a bend. Purchased ceramic wires but is too close to even install them. Not shore why Amazon even carries them.

Cylinder number 4 is horrible, you can't install a spark plug because the runner is too close to put any tools to it, you can't even put the wire on the plug even after buying 45* plug wires

I just love how no where in the description it says that I’d be putting new wires on constantly. The money I saved from buying these headers will be spent on new plug wires from msd. Not cheap. Some of the plugs themselves won’t come out unless the header is off. So don’t plan on reading your plugs. Cylinder 4 is so tight that you have to fight for an hour to get a 45 degree angle plug wire on the plug and then when you do you are just gonna burn the plug wire. Even with the best heat shields money can buy you still ruin your nice new plug wires. What a shame. And a horrible design.

I still have to put these in but we will see if they fit for a LS swap into an s10 they were originally for a 1986 c10 LS swap but I have changed my mind vehicle. But they look great and the welds are very nice. The flanges are thick and they are stainless steel.
