I'm going to look out for a 200 block if poss as I've been led to believe I won't have to long stud it. Can someone confirm this?
I've got an opportunity to buy gt3076 cheap so i'l prob go down that road.
Am I ok pocketing the standard pistons? Should bring the cr down a bit too
Any suggestions on cam choice? Bd14 inlet and standard exhaust?
Headgaskes choice?
Are the rods ok at this spec?
Which injectors will flow enough? Siemens
I take it I'm not in the territory for double valve springs yet?
Who can do me a good port/polish
Or anything else I should be aware of or missed

200 block can either be long studded or not, you cannot long stud a 205 block. at 450hp i wouldnt worry about long studding but your choice. if your on a budget then i wouldnt
headgasket choice will depend on the head and block surface, the head will need to be skimmed and the blocked decked if using a metal gasket.
3076 is a bit big for 450, better off with a 3071r or t38
standard mahle pistons are fine at that power level & yes you can pocket them, the standard rods are good for 600hp + if in good condition
i would stick to standard 8:1 compression
cam choice will depend on who is mapping it, but bd14 inlet and standard exhaust is a proven package - will work well with a ported head
siemens 83's injectors
neil roper is your man for head work

double valve spings will depend on revs, but if its a budget build perhaps the money is best spent elsewhere
get the machining done by someone decent and also get the bottom end balanced
