406 small block review

Okay guys, im new to this board but have often come here when i am in search of engine help, so i finally decided to join.

Heres the deal, im building a 406 small block that will go in a truck (yea its not a hotrod, and yes i would trade it for a 30s chevy coupe in a heartbeat)

This is my plan so far and i just wanna run it buy you guys to see if im on the right track:

400 small block that ive ran before getting bored .030"
Probe dished pistons 14cc
Scat 6" stroker rods
scat cast crank
cam: 12-246-3 - XTREME Energy

Aluminum heads with 2.02/1.6 valves and 64cc chambers
Edelbrock rpm intake
holley 800 double pumper

probably 7qt pan, high volume oil pump

Anyway so far with that setup my compression is 10.3:1 and a dynamic compression of 8.35. That will work with 93 octane if what i have been reading is correct.

My main question is how will my quench area be, stock deck height (which is about .025 if ive read correctly) and a .027" head gasket. Thats .052", and ive read that it should be around .040". How big of a deal is this? I have not purchased the rotating assembly yet so i can potentially switch it to get a bigger dished piston and therefore run a thinner gasket and still stay in the low 10's for compression, but i do like the setup i found, so basically im wondering is .052" killer, or will it not be bad? I want a solid running engine and i want it to be able to turn 8k although it will not get that high very often.
