Speed plate for dual 38's on PHP manifold

I'm not sure if this exists, but id really like to run my billet PHP manifold and vf3 reeds, but local buddies are telling me not to run dual oem 44's on an unported 701 and to stick with dual 38's...

Is anyone running dual 38s on an aftermarket manifold
Or
Dual 44s w a/m manifold on a unported 701 with bolt ons (msd/Jetinetics/bpipe/ada head)

Thanks!
