Vortecs flow approx 234 or so outta the box & are advertised to support 400HP as is,so'with your heads flowing 212,they will need some work.You do have slightly larger ports,so,IDK how much work we're talkin about.That being said,a set of aftermarket heads would definitely be a good investment,or,having someone rework yours.Get pricing for both & weigh the results.Keep in mind,that you having more flow & velocity is always a good thing.You may decide later to up your power requirements. If I had to guess & assuming you will have all the work hired out,I'd say you could buy a good set of heads for not much more than you'll have invested in yours.I would think that gaining another 22 cfm or so would take some substantial work.Not to mention new guides,seats,valves,springs,& machine work.You could probably sell yours to somebody.They're not bad heads.They just ain't gonna support 400 HP as is.
