Thoughts on compression/build

[cuisinartvette]

Let me pick your collective brains on a build...

First off Ive "heard" (yeah, I know...) that the LT5 is not a true 11:1 motor, is really closer to 10:1. NOW-If thats the case.....

-Options
1) Mill heads
2)Custom piston
3)What are the stock CCs on these?
4)Would add a slight bit of cam timing to take advantage of porting. Not 100% on this but heavily leaning towards it. Spring pressures may only increase a slight bit so longevity shouldnt be a problem.
5)Longer/lighter rods....
6)Wont be stroked

Now, for a real zinger....

How difficult would it be to create a solid type lifter, how would that work in terms to adjustment, lash ramps, etc??? Dont Porsche and Ferarri use somethign like this?

Kind of know the direction I want to go, just wanted some input..It never ends.
I promise Im sober posting this
