Only imparting what the blower manufacturer told me. I used to work in diesel engine design and know a little about breathing and scavenging (admittedly my discipline is diesels, BIG diesels) and I suspect there may be a grain of truth in what they told me but hey....

The "working against you" part you stated is completely wrong. You seem to imply that the drop in "psi" is the working against you part.
That is completely wrong. Drop in PSI shows that the heads are working for you, not against you. |

Agreed, you make improvements to relieve pressure through the system then you get a blower that will deliver more air

Absolutely agree on that - the faster you move the burnt stuff out, the better. The Magi guys suggested I go smaller pulley and bigger squirters and ramp it up some more but if I'm honest it's plenty as is.

the 416 will like a ported head or aftermarket head.. around the 255 cc range... it will be happy with a little more compression too...

Going to a bigger valve won't net you much horsepower at all on a boosted application. I would focus on your fueling and go with E85 which will lower your intake temperature considerably and get you a lot more power then spending all that money on your heads for like 10 horsepower.

The stock heads actually flow really quite well. Aftermarket heads dont flow much better than a stock CNC ported head. They do off other things that the stock heads dont, but they are specific use cases for this. You need to know what you want and what your trying to do. Pick your cam, and look at the flow rates up to max lift of the cam you want to use. Compare it to the flow of stock heads, CNC ported stock heads and the flow rate of aftermarket heads. You will be able to make a better judgment on what you want to do and where you want to be by looking at those numbers. And you'll be smarter with your hard earned money. Any place you call is going to try and sell you their stuff, keep that in mind. They're all salesman's...
