I can see a 530+ rwhp can be squeezed easily.
Congrats!

I agree, bump the compression up and you should easliy see 500rwhp. Do you know what the heads flow???

As for the heads i'll have to check i have the #s @ home
those are some pretty good numbers i have the shaved 61cc version of those heads that are also going to go on my 408,I was curious on how they would perform on these 408s do to the fact that they are intended more for stock cubic inch motors.PUT ON A PULLEY AND YOU SHOULD SEE THE 500 PLUS MARK EASILY.DID THEY FLOW ALL THE WAY WITH THAT HIGH LIFT CAM,THATS WHAT I WAS REALLY WORRIED ABOUT MY CAM IS A FMS 246/250 DUR.629-633 LIFT AT A 112 +3 ADV.SO IF YOURS FLOWED ALL THE WAY THROUGH THEN I SHOULD BE FINE.
