I'm thinking to prevent for future clearance issues, the shorty headers would be a better option for me. Thanks for your response and help on this! ![]()

![]() Yes, the bagged Dropmember uses the same geometry as the coilover version, so they would fit with the same magic as mine, probably better, due to the absence of the upper coilover mounts. For me, shorty headers are are not worth the pain that comes with them (blown gaskets, burnt wires, etc). There are a few nice mid-length options out there that will fit the bill and will not lose too much in translation. Hedman comes to mind with their C10 specific mid-lengths—thick head flanges, heavy gauge tubing, and ball/socket collectors. Uncoated I think are under $300

Re: Speed Engineering LS Swap Headers Findings
Out of curiosity, has anyone measured the flange thickness on these headers?
I do not see it listed on the web site. Also, any idea where they are made? |

Re: Speed Engineering LS Swap Headers Findings
They are thick. A friend that is with ECR (their corvette racing side) looked at mine yesterday and thought they were actually kooks (high $$$). He was amazed when I told him they were cheap-o chinese specials.

Re: Speed Engineering LS Swap Headers Findings
Eyeballing, they look like 3/8” flanges. I imagine they are Asia-built, but very nicely done

Re: Speed Engineering LS Swap Headers Findings
Looks like I may have to order a set for my Level 1 DM truck. For once I don’t have to buy the most expensive piece out there.

Re: Speed Engineering LS Swap Headers Findings
Here they are in my 79 Blazer. They clear the frame just fine, but require cutting on the passenger side of the 4l80E bellhousing. I had the same packaging issues some other people have mentioned, my driver side collector is damaged. I've had them bolted up to an LS3 with a 6L80E in the same truck and had no clearance issues whatsoever.

Re: Speed Engineering LS Swap Headers Findings
update. installed mine last weekend in my 67 with a 4-6 drop, 5.3 dbw with 4l60. fit perfect, no trimming, no cutting no fabbing. nada... cleared the tranny and the starter no problem.
only part that sucked was I had to remove my brake master cylinder and booster to get the driver side in, now I gotta re bleed em again.

Re: Speed Engineering LS Swap Headers Findings
I bought a set of the long tube 1 3/4 based on this thread.
5.3 with 4l65e and 3/5 drop in the truck. The box showed up a little banged up but I just grabbed a crescent wrench and straighten things out. The headers fit with no issues. I reused the factory trans cooler hard lines, so I needed to make some "adjustments" to the line to get them not to touch. I installed the passenger side from the top. Drivers side from the bottom.

Re: Speed Engineering LS Swap Headers Findings
I purchased the upgraded gaskets with mine, but not sure which gasket goes against the block and which one goes against the header. Haven't looked at them that closely, but it dawned on me while looking through this thread. Anyone have a pic or explanation on how I should install them? Thanks,

If you got sent 4 gaskets, then the upgraded ones should be the multi-layer steel versions. Without seeing what you have, The multi-layer gaskets should not have a specific side that goes against the head or the header flange...Just use one multi-layer gasket between the head and the header flange.

Re: Speed Engineering LS Swap Headers Findings
Thanks aggie. I hadn't seen a two gasket set up, so I was confused. I guess they just sent the standard ones and the upgraded ones.

Re: Speed Engineering LS Swap Headers Findings
I am wondering the same thing. I ordered a set last night and added on the "upgraded gaskets". When they arrive I will post pics of theirs VS. stock GM.gaskets, although I am running a 5.3 LT from a 2014 truck, so they may be different than yours anyway... I dont know what setup you are going with.

Re: Speed Engineering LS Swap Headers Findings
I don't have them installed yet, but for those asking about the gaskets I have a set of the shorty headers from Speed Engineering. Overall they look like quality headers for the price of them. They come with the standard "paper" gaskets and the upgraded gaskets are similar to the OEM style.

Re: Speed Engineering LS Swap Headers Findings
Here's a couple more pics to show the quality of the shorty headers.

Re: Speed Engineering LS Swap Headers Findings
So the multi layer steel gaskets are a gm product.
Also my headers arrived like the rest... Did yall receive header bolts with your purchase? Im guessing mine fell out of the box if they were in there in the first place. ![]() |

Re: Speed Engineering LS Swap Headers Findings
Has anyone used the f-body long tube speed engineering headers on a C10? I have an fbody oil pan and want to find longtubes that don't have below the pan much if at all.
