I just put a work order in for the machine shop to put together my new heads. Pro topline torker heads 167 cc intake runners 2.02/1.60 stainless valves 67cc combustion chambers the heads are then going to be slightly shaved and mildly ported.....this should make a difference since my current heads are just old stocker 1.94/1.50 76cc heads...I am running flat top pistons and a 278 duration .467 lift crane cam, also a holley 670 street avenger up top...hope this helps out the horse power!!!

Those heads are a great value for the DIY porter,the cross section of the runner has alot of material that can be removed if so inclined plus the water jackets are improved and have thick decks,machined for screw in studs,flat V/C rails ect. Some attention to the combustion chamber is in order to increase flow if the castings were like mine. They are a good bang for the buck but in my opinion do need some work out of the box. Now I went overbored and have a killer set of heads but alot of time in them. If I had it to do over I would buy Dart Pro 1's spend another hour on them and be done.

Anyway for your motor I think you will be very pleased with those heads. Use GM rocker studs not ARP,if you use the ARP's you will need to chamfer the holes so they will set flush when tightened because of the step made into the ARP's
