Best fittting headers for 69 340 GTS ?

Ok so if TTI's or Doug's work great with 340 P/S a-body setups, what if you have Eddy RPM heads? I've heard due to the spark plug angle change, this might pose a problem?

I've also got a lead on some lightly used Hedman tight tube headers for cheaper. I've read old posts where some liked those (except for connecting pipe to the collectors) but same questions on Eddy heads for these?
