I didn't say I bought them, .. but I did have a set come through my shop,
current spec head, originally done by Fultz, .. they where here for little
over a week just over a month ago.
3.5" csa at the opening, other specs I won't post in public, . ..
as for thr R07, .. I hear it's a killer head, ..
I know of a current development that's seeing 380 cfm @ .500"
and 450cfm @ .800" Nice strait port not the offset opening like the SB2.2
