My statement is not opinion, it's well accepted fact in the industry.
NASCAR starts off with a head that is reffered to as a porters casting (ports are very tiny, on purpose), or its a full billet head. As I stated, that is different from starting off with a finished cast OEM head.

Actually it is a mater of opinion, just because of the simple fact we don’t agree.
The heads on my car are hand ported by me, so I know a thing or two about porting.
when it comes down to equalization of flow from one port to the next, it’s almost always guaranteed a CNC job, if done correctly, will have flows that are more equal than a hand port. That’s not to say the hand port won’t actually flow more. This is a matter of testing. 4 piston has some of the best heads around, they know their stuff.
If it comes down to 5~10 cfm I would take the head with less flow if it was balanced more evenly. Although I seriously doubt the 4 piston heads has less flow than the Head games head.
If you don’t think it’s a matter of opinion then search “Hand port vs CNC” most who are saying that hand porting is better are vendors who hand port, just sayin.
Yep exactly! Even though I’m sure 7-800wtq feels nuts
Lower numbers were for the low boost map. 27psi e85
thanks for the reply I was just curious to see if it was pump gas as I’m looking to go with a 6446 since I have a 2.3 engine and don’t have readily easy access to E85.
Torque is as such because it's a 2.0L. I built a 2.2 6466 car that made 620wtq, and 2.4LR 6466 car that made 665wtq. ER stopped at 665wtq on the hist because that's the most they have made on a 100mm crank...lol. Car made 800whp with 35psi out the top.
The drivetrain holds up fine. It's the motor that will live a shorter and shorter life as you go faster. The ER drag car that went 7's made 880wtq, and it runs a stock ACD transfercase...
Your vent setup is way small though. You really need to 10an lines running off the valvecover to a VTA can. Looks like you have one 8an line, and the the stock PVC valve. This also likely why you're filling the catch can.

Previously, I had (1) 10an line coming off going to a vented can. but since swapping to the Skunk2 manifold, it no longer uses the pcv valve on the backside. So I have a sheepey catch can coming in And I’m running another 10an line off the back of the valve cover where the pcv valve was.
Does that make sense?
asking because the car is smoking a ton since swapping to this intake manifold and made me wonder without vacuum from the manifold how is it pulling some of that pressure out. But then again I thought maybe it was my filled up catch can.
