  • They fit well, easy install. They fit well, easy install.
Really wanted a full length set of letters for my 83 Chevrolet C10 project, however was worried about ground clearance that's a truck will soon be lowered. These headers fit perfectly, the only issue I had was a supplied header bolts or for a small block Chevrolet not an LS based engine, not a deal breaker but would have been nice to have brand new hardware. Overall they look good and fit like they should. ... show more

  • Perfect fit for LS swap
These fit nice and tight to the block on my LS swap. Depending on your application, you may need to trim a tab off of the bell housing.

  • Not recommended.
So I'm quite pleased with the overall construction of this. It is a tight fit at the transmission like others said so I'm not upset about it. Nice welding inside all the flanges which I was concerned about seeing the pictures the outside wasn't fully Welding, it is on the inside. The individual ports are bigger than the stock head ports which is great. Overall pretty happy but the engine isn't inside the car yet so I'll update if there is any fitment issue. UPDATE The headers clear the steering box on my nova. It's very close so depending on engine mounts it might hit. Weird part is, it hits my passenger side control arms bad. Even bought tubular to try to fix the issue and still no. Had to heat it up to oval out the tube. Even worse is the actual pipes have multiple cracks going on them on multiple of the runners. The metal is a lot thinner than it states. I've only put them through about 100 hours of run time. I would not suggest getting these except as a very temporary thing if at all. ... show more

  • Tight clearance, possibly bent? Tight clearance, possibly bent?
I don’t want to leave one star but was hoping someone from the company tell me if this is supposed to be this tight to the starter side of the block. Header looks almost bent wrong on this side compared to the other side. Help?
