Question 5.3 heads port limits....? 225cc...?

I recently picked up a car that is built (347, ms3, etc...) and previous owner(not builder) said it has 5.3 heads ported to 225cc.... it does have 5.3 heads. But I'm unsure if they can actually be ported that big!?
Anyone know if they can be?

Yes they can. I would be more concerned on who ported them than what size the runner is.

My ETP 5.3's have 230cc intake runners.
