Frustration: finding out that the equal-to-within-one-RCH, perfect fit and radius set you made produces 5 hp less than the coat-hangar J. C. Whitney setup your friend has. 50 years ago Mickey Thompson did a demo in which he heated up the primaries with the engine running, and pulled them up and out 60 degrees. Result: +50 hp.
It's not science yet, there's too much random and unknown to know what works. Read Gordon Blair on exactly how many waves are present inside the primary = there's constant traffic in both directions.

Been there done that. I know make the trip to Kingman and Greg Hollman at REF. He gets them done in less than a day and they look great. Best part is cost is not much more than I pay for materials to do them from SPD, which is who he uses as well.

Lol. It took me over 8 hours to modify 2 tubes last year to get a diaper on my black duster. And it has lots of room

Well the only thing they do at REF is build headers. So that defeintly helps for sure. We have done a few sets and seems to take forever and the cost of materials is really high. So from now on it is REF or Performance Welding for me.

So from now on it is REF or Performance Welding for me. We ran into the same thing at ATI were I was a Millwright at the time for 30 years. They forced a 1.00 an hour raise on us and instead of just Millwright work they sent us to limited schooling to become welders, hydraulic repair, carpenters, pipefitters, diesel mechanics, riggers, and railroad car rebuilders. Everyone was out of there element and I retired 3 years later. A skilled craft is one thing but to master 9 crafts is impossible in such a short time period.
