block hugger headers for SB

I'm making a spring wish list and found a set of street rod block hugger headers at Summit. Has anybody tried BHs on a late B?

One thing to take into consideration is that almost all Moapr blockhugger headers meant for street rods will not work with Mopar k-frames. They are intended to be used with MII and other aftermarket frontends. Check with the mnfr before you buy them.

Yea, that's what I'm afraid of. Reg tube headers are a pain sometimes but I may have to go that way.
