Something most guys don’t understand is the rough surface inside the runners in heads/intakes actually flow better than if they were smooth or polished. It’s the same principle as why a golf ball flies better with the dimples. Obviously if there’s giant outcroppings, extremely rough surfaces, or partial blockages are not going to help you but shallow rough surfaces will help flow.
you need new pushrods, and depending on what rockers you use, you will need new valve covers. These heads are not plug and play. you will spend at least another $500 in parts if you decide to make the switch.
what is the expectation for hp/tq gains with heads cam and keeping the keg and the expectations for hp/tq with the air gap heads and cam? I did a turbo ls1 swap on one of my jeeps it's too much for the trail so im toying around with selling it and building a jeep with 5.2 or 5.9 and I'm looking into the cost associated with making 300-350 hp crank. BTW great video great info. there is very little info out there. Thanks
Did you bolted on these heads straight out the box on your engine or did you bring them first to a machine shop . i am thinking of purchasing the heads assembled and can i put them straight on my block whitout any problems ? Thanks
You can add compression with those heads... aluminum absorbs way more heat than iron and can actually harm effiency in some cases by over cooling the combustion chamber.. therefore they can tolerate more compression and regain efficiency 🤓

Just a note, you will need new rocker arms for these heads. Im going to find out soon if you need new pushrods.

very cool.
Texture in a intake port will always make more power than a smooth port. It's all about wet flow and keeping the fuel in an atomized state.
Dont forget about atomization in the intake runners need a lil to mix well
