C.C. an intake port on both, or read the Screamin' Eagle catalogue, it says it is smaller.
As for the "rant" if nobody knows the cam specs how do they know if the dyno numbers are good? 
My opinion only, and I have my own dyno and lots of pulls. But I can't correlate to anything else without all of the facts. I expected to see someone post cam specs, hasn't happened. Bye now.   TIMINATOR

No need to read the se catalog or CC the port

Mva heads have a 93% throat id,2.12 intake 1.635 ex valve

110 heads are 2.08/1.623 and a 90% throat I'd

Running the CNC program for a mva head in a 110 casting it cleans up about 80%

Leaving a unmachined spot behind the guide and a dime size spot on the wall mirrored on both heads

So you must have read that

Not all that hard to figure out if you really wanted to.

(93% is too big. You'd need a 2.19 valve to make that work)

Still trying to figure out how a 110 head is larger (port volume)than a mva head
I have had them side by side and measured. The floor and bowl dimensions are very different so they end up close to the same.

Yeah... you are right. Someone can measure them and get the numbers. Just not me 😉

Measured two sets side by side in the last 6 months. The ones on my bike (I bought the CVO 110 Breakout new as I also bought the MVA heads new)and the ones we put on a customers bike that he bought new, also a CVO110. Everything new untouched. I believe what I saw and several peeps verified. Both bikes picked up top end HP and midrange around 2000- 3000. Not saying that the MOCO or any other MOCO has had any running changes.  You believe what you see. We're cool.    TIMINATOR

Here's my opinion. Take it or leave it...

Measuring and comparing port volumes (especially on these engines) is not that meaningful.
The CSA (cross sectional area) at the critical point(s) is WAAAY more important.

CC'ing Two ports and then trying to draw conclusions from that is a fools endeavor. It can, and
will, mislead you every time. It just isn't a meaningful enough measurement to draw any
specific conclusions from. (other than one port holds more liquid than the other. It doesn't
mean chit)

I rarely ever CC a port. If the air speeds, (Actual and theoretical) are where I'm shooting for then
I don't give a $hit about the port's CC. I may check it just to see what it is, but I NEVER use it
as a design parameter.

CSA and air speed is what counts. The total CC is a byproduct and a misleading one at that.

Matt 100% agreement. Tim if your customer likes those mvas they could have more with a properly ported 110 head. The MVA needs work but can be brought around but it takes larger valve and more work and then the csa is big and it must be fitted to a large motor to get it to work best.

(Ported 110 heads would be my first choice for a large CI motor)

MVA heads are way too big imo. I've had to weld up the ports to make them
work right, I don't like jacking with them.

I HAVE DONE SOME RESEARCH AND MY HEADS ARE THE 110 WITH PORT WORK AND IT SEEMS TO GET BETWEEN 12-16 HP MORE THAN THE MVA HEAD TQ ABOUT SAME

Here is a question.

110 motor comes with SE 110 heads
120 motor comes with MVA Heads

Which head do you think matches better to a 117?
Would you swap the heads on the 120?

I would not bank on 12-16 horsepower for many reasons but I am not saying that is impossible,  just not consistantly and repeatable with heads gone by all shops. Synod matter too. There are some generous ones out there

Moreover, compare the TQ curve over the entire RPM range. That's what air speed does for you. !muy importante!

(Was that dyno verified? Or butt dyno? Butt dynos lie even more than real ones) haha
ps: you can't make more HP without increasing the TQ (or RPM). It's one or the other.
