If it's in cad/drawing already it is way easier to modify than to start from scratch. Yes a custom camshaft would need to be made its not rocket science. You would need cams made any way to work with our cam gears. Again its not rocket science, someone that knows what there doing
.....and all of that is in cad.
heads cams, gaskets, manifolds etc.
if someone is willing to spend the coin for a 4piston head anyway (it starts at 6000$) and do a ton of custom fab for a racecar, whats a little bit more lol.
the setup would be to get 4 piston some dodge 2.4 cad stuff and make a hybrid head that bolted on and used SRT cams and followers with the K series ports. it would probably be a one off 15k$ head but man would it perform.

Masi head?

$4000-$5000 to print in metal. That does not include the cost to have 3D design made.
The stock head on the Maserati TC with the 16V engine allegedly flows more than ported TIII heads. It is also cam on bucket, so say goodbye to lifter problems. Need to turn crazy high RPM? OK, that's not a problem either. People shy away from them due to the rarity and high cost to build one up vs. a 2.4 or TIII, but if you really want high performance, then they're where it's at.
Oh ok, I dont want to change bottom ends or auto transmission. I'm happy with 2.4 aluminum long rod setup, just want to get a better port design, no more lifters, and thicker deck to prevent flex.
if one wanted to make a billet head I think doing it in layers about 1-2 inches thick to create a stack that then makes up the head .. when stacked might be the "easiest" solution
bottom piece is deck surface , combustion chamber , top side of roof of combustion chamber and the floors of some of the water jacketing
second layer .. more water jacketing and port runners & valve bowls
and so on as you go up

the exuberant prices of those "rare" parts doesn't help
I know I want a 16V CB crank .. but I'm not interested in paying 1000-1200 bucks for a crank no one wants to use
but for 5-6 hun ... it becomes a nice "billet" to start making a "real" crank outta... and I'd rather invest the difference into that huge bill coming from the machine shop than a guy who allows parts no one needs to collect dust

lol,
well .. you work on that and I'll try to not find out what it takes to snap a 16v crank ... doing a few thousand laps .. hopefully
- I do have an acquaintance who could offer some comments on the cast cranks , ncb bottom ends and cracked blocks , if I ever see him again...
I'd like to affect the nature of the way the car drives also as part of the "experiment" as a similar mass revolving around a smaller center should spin up and slow down much differently than the same mass over a larger radius as mass is greater the further it is from center
and I see a lot of places to hack weight off that 16v crank , almost twice as many places in fact and with lighter , stronger rods , 4 bolt caps and a common block it makes some sense to try the "premium version" of the crank too as the double weighted crank is all about reduced stresses and improved stability of the block's mains
anywho sorry for the off topic.. "back to the top.."lol

While I do enjoy this platform the thought of dropping $6k on a cylinder head in a car that's worth half that makes no sense.
At some point it just makes more sense to move to a different platform.
unless the low cost of the car enables you to spend "the money" elsewhere
we can find good cars and parts cheap - not so if you needed a cuda , challenger or road runner with a worthwhile shell , just to start
I know I can't find anything else <<that good for the same 25hun as <<
