There has been some discussions with Dart as to making a pattern for 165 CC intake runners. Use the same part# for NHRA approval process. Then you could get to 161 CC applications as well.
There are guys running aftermart heads with no modifications to runner volumes...
Bigger intake runners don't always mean the you will be a faster.
