milling heads for comp ratio increase

I sorta skimmed through these threads so...
Are these the oem heads and has this motor been built B 4?
in any case B 4 you mill
cc both heads at both ends
your head miller can then set up to even up the cc's for all 4 end chambers
so you do have open chambers? too bad no quench
you already have adj rockers and solid cam is ok with you?
you can blend your bowls yourself
B sure your guides are in good shape- I use K line inserts with the inside knurl to hold some oil and use Viton seals
If you are going to higher than stock lift B sure to check retainer (keeper) to seal clearance B 4you take your heads apart
I'll try and read this thread later
AFB or AVS good choice for your motor
of course all the 318/ 360 comments apply
you can get HP based on heads and rpm
but you get it at a lower rpm with a bigger motor
