I am with most the guys here for touring engine in not going full pressure
I would add a Filtering system as it can only add to the life of a engine
I would also dynamic balance everything and consider a harmonic balancer and counter weight crank
I try to make as much power as possible in the low to mid rpm range with cam valves and head
as I believe you want to up hills at 2000 rpm in top gear and not 3000 rpm in 2nd
