THose heads will not do it,the vortecs flow more than they do,only a small amount ,but there half the price.. and the vortecs are good to about 400 hp with a very good tune and bowl work.What are you going to use the car for ,track,street ,daily driver ?I would use the vortecs a rpm airgap and a XE 268 comp cam.a little under 400 ,but it will make lots of torque ,what a heavy car needs to get movin.That cam you showed will not make much torque or hp untill the rpm starts getting pretty high 4500-5000 before the hp would climb above the vortecs,not good for the street, Race track only the team g and big cam might do a little better in the 1/4 ,but not by very much.Usually not many times you can rev to 4000 on the trans brake at the stop light either.The vortecs need new valve springs and some minor work to make them handle a cam with a lift that much over .460
