round port headers on D-port heads?

[Rob Weiskirch]

Guys I have access to some nice JR 2" round port headers for my '67 firebird. Trouble is, I run D port heads. It seems like guys have used adapter plates to make this work. Anybody out there ever done this? Other solutions? (besides round port heads!) Thanks, Rob

Jim Butler did a set yrs ago...Jack Gadash ran them for a few yrs..but more trouble than its worth..he put on a set of BRANDWINE ported Ram Air 4 heads and car pick up a bunch...

A friend is running the Hedman 1 7/8 D ports for 70 TA and they have an adapter for them to be used on the head. The end ports seem to have the same pattern as round ports but not the center ports. Possibly use it and convert the center two ports(weld new stubs) to convert.
