Thank you!
Hopefully he has his car ready for St Louis. I've been in those shoes and they suck.
Thanks,
Mik

Are there important dos and don'ts when building them?

Header builders seem to be a dying breed around Ohio, so we may have to try it ourselves.

I build my own headers; I use a program called pipemax to design them for size and length. the program also can be used to build step headers. To answer your question when building a set to fit in an engine compartment and maintain equal length is pretty hard. Getting access for plugs and starter is just as important. On a dyno not sure what the loss would be on different lengths, but I seldom see any factory-built headers that are even close. I am a big believer in step headers and have seen gains on the dyno.

Call Mike Schaefer at The Mod Shop - Lakeview, OH

He builds some awesome headers. He built the headers on Doug Duell's stocker and his SS challenger for reference.

937-935-9898

He has done a lot of work for me in the past. Great guy to work with.

Does equal length mean equal flow and pulse timing?

Seen a championship Pro Stock with unequal length primaries

equal length in our cars, cars with the firewall in the stock location, stock frame rails, etc. means sacrificing fit, ease of installation, spark plug access, ground clearance and in some cars, having to remove and or cutting the inner fender wells all for nothing on the time slip.

I just went through this in my Cavalier. I ended up with equal length and in firing order. There was no way I could get the length I thought it needed with the tight space. So I had him put the proper collector length collector and connect the flange.

I will say this. Equal length tubes with a LS firing order (SBC), makes a crazy looking header. Have pics if interested.

Chad, do you and any pics of the final units you are willing to share? I am not following the firing order comment you made. Thanks
