Ok guys i pulled the trigger on my build it consists of a lq4 stock bottom end ima be running gm mls head gaskets with 799s milled .30 with 228/232 cam with a NNBS intake what are yalls thoughts on it and i would like to know around what CR this build will be at. i havent seen a build like this.

 

Anyone??

 

I think the compression ratio will be around 10.5 with stock 243 heads on a lq4.
Milled, I dont know, close to 11:1. Kinda just a iron ls2.

 

In order to get the CR, you will need to know the chamber size. what is the chamber size after milling the heads? after know this you can use an online calculator

 

It would drop to essentially a 706 head chamber, so 61 cc give or take a 1/2 CC

 

Thanks guys i just needed a ball part in CR..i been looking for head gaskets but i keep finding different sizes anyone would know what size i would need .51 or .41

 

Depends on the compression you're shooting for. There's a calculator on Eagle's website that is way helpful. You really need to volume check your chamber if you want to get accurate numbers. I'd also check PTV depending on the lift of that cam.
