Whats up HT. I'm building my lsv and just picked up my gsr head and was curious about my CR being too high. Here's my setup:

Head
Gsr
Itr valvetrain
Itr intake cam
Skunk 2 IM
Rdx injectors

Block
B18b1
Ls rods
Ls crank
P30 pistons
All arp studs and bolts
Oem ls main and rod bearings

Please if anyone has any info on this setup I would appreciate it. And I did research first before asking lol

 

You should be at about 12 I believe, the pr3's would have you at 11.6:1

 

I thought it would be more. Thanks a lot. How would I figure this out? Compression calculator? Don't really trust those
