Port matching heads to headers

Slowly, much like the repairs to 2511, my engine is being assembled, and my engine builder posed a question I do not know how to answer.

I am using the 4-barrel CHI heads and blue thunder intake, 404 stroker, GTS tri-y headers.

Exhaust ports on my heads are not CNC machined but remain as cast.


What sort of heads to headers port matching should be done?

None? Match to gasket? Or???

Any wisdom you can provide is appreciated.
