hedman "tight tube" hedders?

Does anyone know if these will interfere with the firm feel short ratio pitman/idler arm?

I actually just talked to dick from firm feel today about this. We talked for a little while and he said if you can get the mid Pipe above drag link and tight to the firewall he thinks they will work. He also said he got a set of Dakota headers and is going to to try and make them fit. That would be cool if firm feel did their own modified SS Dakota headers.
