thoughts on this build? what i'd like to do is get my 3rd gen some gen3 power 
now here is the idea i got so far...
6liter lq4 or lq9:
now what is the difference in pistons on these motors and do they have the crappy rod bolts like the ls1's did....i am needing to know since it will be out of the car if it would be in my best interest to arp the bottom end right away if i can?.....if the stockers are strong and the bottom end can hold 500rwhp and 6500rpms safely i will do that.....compression ratios for the two?....stock head combution chamber size? (this motor is only being used to get the car driving and i am wanting to build a aluninum long block)
heads:....i am wanting to go with these heads because of the price and they are just plain awesome...since the combustion chamber ize is 70cc i was looking to find out if i milled them down a little if ptv would be a result?....the cam i plan on using is the TSP MS4....this is .649/.609....if the lq4/lq9s use a slight dished piston could i get away with a mill on these heads to bump up compression?...what would you recommend for head gasket thickness...i know i need a gasket with the bore of 4.065
cam:i wanted to use the TSP MS4 as stated above...now would this be over kill with the 6liter/l92 heads and l76 intake?...i am worried about the PTV as stated above
intake:i am using the l76 of course and was wondering since its coming with 39lb/hour injectors if those would be more than enough for the above combo?
any guesstimate on the power i'd make?...i am looking for atleast 450rwhp

As far as the rest of it, 450 shouldn't be a big problem with the l-92 heads. Go with a bigger split on the cam. l-92's have a relatively poor exhaust flow rate so you will need to crutch the exhaust side with more duration. Go with a custom piston to compensate for the bigger valves and use it to bump up the compression while not giving up any on the ptv clearance. Hope this helped..
