I've been getting confusing advice as to whether the Header and HFCs will be good or bad for the SC kit.
Have heard Stillen strongly recommending against the headers (loss of psi and lean A/F), as well as, headers working well with the kit. And HFCs not being able to take the extra heat.
I am seeing some member here running header+HFC with the SC kit.

Any advice?
