twin timing chain will wear less when you have large cam.. but i have never seen a single chain break.
maybe there is no benefit? i would use twin chain with big cam and heavy springs.
exhaust ports are beneficial to port out.. maybe 2mm on walls and roof, but nothing on floor?
intyake ports may not be hugly beneficial, but unshrouding valves is always good
