5.3 turbo head choices?
 

Okay guys, I'm having a little trouble here. I'm building a 5.3 lm7.

First of all. Here is my setup.

Eagle CRS6125O3D 1.125 length .927 wrist pin
Wiseco k474m965 -2cc flat top pistons .927 wrist pin. 3.800 bore
KING main and rod bearings
Wiseco 3805HF rings
Master power t76 1.0ar

I'm trying to decide what head I want to go with. According to wiseco, a 61cc head will give me 10.4:1 compression ratio. I really don't want to run a turbo on that high of a CR. I'm not quite sure what head to use. I was thinking 799 heads (64cc) with a thicker gasket. Any ideas what head I should use? I want to be around 9.7-10.0:1 CR. opinions are greatly appreciated

Either 243 or 799 heads at 64cc with GM MLS gaskets will be at or a tad less than 10:1.

799s will get the job done with MLS head gaskets.
