Valve springs for howards cams

do we know real cr?
with al heads and that 267 cam some woul go 10:1
if daily driver and 87 octane try 9
hp does not go up much with cr but driveability does
keep the quench tight if piston deck is sent- makes more difference than 1/2 point of cr
if you have to back- go to the voodoo 268 better than comp 268
so you have two good choices for 268 class cams
do show your cr calcs
cheers
