Applicable to supercharging is the port job I have done : open up the exhaust side slightly and polish it. Smooth off the ridges just under all the valve seats going into the port. The stock intake ports are small to maintain high charge velocity and provide good torque at the bottom end so making them much larger is not a good idea for a NA engine and probably not either for a blown engine.
Who says you need an intercooler ?
Intercoolers are needed for turbos (heat transfer from exhaust side). If you run 10psi or less of boost you dont need intercooling.
Stock cams provide no overlap which is great for kompressor engines.
Are you looking into an Eaton M45 per chance ? It looks like the right ticket for this engine.
The downside to all this is that at 10 psi you cant expect much more than 230-240 hp
Good luck and keep posting

K so the stock cams offer no overlap, you can easily adjust this since its a dohc, any way, In NA form how would the no overlap work out to??? ie more top end or more torque???
i have this engine ina 280CE and i retarded both cams 4 degrs each which resulted in gr8 topend power above 5000RPMs but no low down what so ever, whats your say on that.
and with 10 psi i would expect more than 240 hp but i wmight be very wrong, my m103 300 w124 has abt 10 psi boost and it is well over the 240 hp mark and i can even claim its a tad over 300 hp. but thats a diff engine.
