There was a budget for this build in the beggining, that fell apart pretty quick. The gasket was apart of the build from the gate, and it's not anything significant in cost between the cosmetic MLS and a felpro, I'll spend the extra $70 to run the best head gasket on the market.

You think a MSL is the best gasket but they can be a finicky *****.
Its ridgit, by design it can`t make up for any imperfections in the mating surface. Better be sure your surfaces have the correct finish are completely smooth, flat and straight and hope that when you put them in its an extremely clean environment.

I would hardly call the port mismatch "hackery" lol, is it Ideal to have everything perfect port matched sure. It would take hours to modify the square port intake to match, but for what gains? Its already been stated that the gains aren't worth the time/effort or money. Do you have any data to support other wise? Will not port matching make the engine less reliable or cause damage to it? What is the exact benefit or gain power wise or performance in the boat to port matching the intake to the head in this application? What makes this "Hackery" and so wrong to you? Data supporting what you are saying would be ideal, cause it has already been said that its not worth spending the money for an oval port intake or the time and money to modify the square port intake to port match by someone that has the experience to support that answer.
Mike I still haven't gotten a response from you on why I shouldn't use a MLS head gasket on my build?

Heres my data:
Does that look right to you? Nice wall the air hits , that looks great for air flow and turbulance .. good luck with that.

Do you really think that square port intakes weren't used on oval ports all the time back before oval port intakes improved? So every oval port head are the size as the ones pictured? What heads are those that are pictured there? Those ports look pretty small. The mismatch will be assessed, and if it isn't acceptable the transition will be smoothed out a little to make it acceptable. Is turbulence in the intake always bad? I have good information that it's not always bad.

They're also easier on the surface of the head long term, which will result in less material having to be removed when it's time for a freshen up.
As far as the mismatch, why don't one of you Internet engine experts take a look inside the intake port of a Whipple intake with the intercooler installed. Or do a little research on what's actually going on with airflow in an intake port. Do you think it just flows through in a continous direction like water through a hose?

They can leak...Some guys put em on with dry others swear by cooper spray a gasket or hylomar, some others take the layers apart and spray each layer,some put rtv around the water passages ... Felpro used to put a Viton rubber coating on theirs but I did not see it on mine .. you need a 50 RA or better surface. My point is if you don`t need it, you don`t need it. I contemplated not using it on mine after reading some of the issues people were having.It`s a better gasket for sure but it come with some quirks.
Edit:
I`m sure the mismatch is fine, it`s just something I would not do.

Do I have any data? Why do I need data?? I don`t see any data from your sources either except some one word replys and we`re all supposed to bow down and take their word as gospel? Not me, no man knows it all and I make up my own mind.
Heres my data:
Does that look right to you? Nice wall the air hits , that looks great for air flow and turbulance .. good luck with that.
