clearance issues with the spark plugs

May 18, 2013
these headers are not to bad but you will have to put some dimples in them to clear the spark plug boots. I have a small block 350 that I put these on and the runners almost sit right in front of #1 #7 #2 and #8 plugs. the inboard plugs are fine on clearance. not happy that I have to modify brand new parts to make them work.
Pros:
  • Price

Junk not worth the price.

February 20, 2013
I have bought items in the past and have had no problems. One of the headers will fit both sides with no clearance problems. The other header fits so tight against number 3 and 5 or 4 and 6 whichever side you place it on that it will crack the plug. My wife bought these as a Christmas present two years ago and its to late to even contact customer support. I could take a hammer and put a dimple in it but that is not going to look good at all. I am building a street rod, not a junk rod. Also the runners came out past the flange and I had to grind these down flush with the flange. No option for the temp sensor in the head either. Just don't buy these.
No, I would not recommend this product.

Junk, plain and simple

February 07, 2012
Opened the box to rusty headers, noticed the runners came out past flange, had to mill the flange flat. Tried to install the bolts are VERY hard to get in and torque, Spark plugs are IMPOSSIBLE to install! Started the engine, blew out the cheap gaskets with only headers on.. how is that possible?! No options for head temp sensors, not good. Mocked up the exhaust, got tired of the leaks and removed, in the process dented a runner, cheap cheap cheap. Called Cust. support to no avail. 1st and last product from here.
No, I would not recommend this product.

Yes these can be flipped upside down in order to route the exhaust up through the hood. You may need to do some modification to the header flange in order to clear the water plug/sender in the cylinder head.

Part # 9300100 These headers fit many applications and are a smaller 1 ½” diameter tube to primarily work on the round port heads which you will need to verify. Will NOT work with angle plug heads and collector to head pipe clearance needs to be verified by some basic measuring. The dimension furthest out from the head at the top is 3.75”, from the top of the flange to the bottom of the collector is 10”, and the collector sits within an inch of the block right at the pan rail. These headers will not clear clam shell style motor mounts.

Tight-Tubes Extension Kit, Mild Steel
(Part #91013385)
                        Using this kit makes the hook-up of your exhaust system a snap! The 2-1/2" diameter, 16-gauge, mandrel-bent tubes curve back at a 90° angle and are offset outward to clear the bellhousing and starter.

Just trim the length, weld on the 3/8" thick collector flange (included, with gaskets) and you're all set! Works great with any tight-fit headers. Header not included.
