I think that you are forgetting about the B16 head will raise the compression also....I am thinking that with the pitons being 10:1 and the head gasket change and the head will bring it to atleast 11:1.....

if your pistons are 10:1 with an ls head then it would be like 10.7:1 with a b16 head and a 2 layer headgasket...just check out on c-speed if you don't believe me..to get 10:1 with a ls head you would need a 2cc domed piston after you get that just change the head configuration along with the gasket and bam 10.7:1

No but most ppl arent that good with math or want to take the time to calculate it, but there is a site that gives the formula if you want to calculate it yourself! I think its......
