Depends on how in the weeds a ported B230F manifold still is, I suppose.
Either way you still have a Volvo 8V head.

So klr142s General Leif makes like 155whp (so assuming about 180 crank) with a modified k-jet intake (bigger tb, and some smoothing I believe).
That same engine, head, and camshaft combo will usually make 220 crank hp with ITBs or DCOEs. So that's a significant amount of power on the table with just the induction side.
A well warmed over 8v head can still do 260+ crank hp...
