Default 383 LS1 parts give me advice

I am building a 383 LS1. I have narrowed it down to these components.
I would like input for people that have done this and sponsors that want to sell me the parts. I want to buy the Rotating Assembly and heads from the same person so I know that they will work together and have the correct compresson ratio. I need a good cam for street type lots of mid-range.

Lunati LS1/LS6 Rotating Assembly
Stroke (inches) : 4.000"
Rod Length (inches) : 6.125"
Bore Diameter : 3.903"
Compression Ratio : 10.6:1

stage 2 ported 243 heads

Fast 90/90

Cam/valve springs and retainers

i've not done it but i'd say something in the 23x/23x range on a 112 or 110 with xer lobes should be a decent choice. are you set on the 10:6 scr ? you could probably get away with alittle more scr depending on your cam choice and octane.

you could save some major coin going with an eagle rotating assembly.

Also I would recommend HPE for building the engine -------------->

I don't really want to go any higher on the compression ratio. I travel in Mexico and do not always have the best fuel available.

you need to pay more attention to your dynamic compression rather than static.
