tough 3tg

hey guys im starting the building of a reasonably tough 3tg. its for street use but itll hopefully see the track a fair bit too. with the 3t-c rods and crank what are areas that need to be looked at. full balance is already known.
should i have the crank stress relieved or not really nescessary?
work to rods? shot peen, linished etc?
am building it work well with a head and cams package ive just purchased. see below
"Yamaha stamped 2tg fully reconditioned head. It has new valve seats etc etc valves havent been changed but i had them double checked. It is a 11111-88260 so its the 'desirable' head. Its shims have been set and checked for high lift cams that have been built up and machined to aggressive specs, i think they are wade 584A grind ex 80.5 - 45 deg, advertised duration 305.5,duration at .050 - 259, lobe lift .427",Valve lift .415". Intake 48.5 - 77deg. "
also will vernier cam gears be needed to make the most of the engine? anyone gotten any made for a 3tg? experiences, prices etc??
Pistons? should i get forgies? or will the standard 3tc pistons hold up to a reasonable thrashing. ( remembering visits to tracks)
are there any other areas i should look at strengthening in the 3tg??
this will be an injected setup using the 88262 2tgeu efi manifold etc untill i can afford ITBs so will this manifold etc flow enough? im thinking yeah cause its no turbo motor. injector size. ive herd of 3s-ge injectors being used? will they flow enough?
for fueling im thinking just VL turbo fuel pump, some sort of pressure reg ( ideas??)
will i need bigger efi lines or will the standard lines from the 81 TE71 liftback be enough.
sorry for the length of this post but i thought id be better off getting it all outta the way in one go.
cheers for any help
