That is quite a bit of duration IMO. I think the lift ought to be okay though (Feel free to correct me on that). How high were you planning on spinning it?? Probably pretty high, but if your confident the motor can handle it I say go for it. What do you mean heads reworked. If you had a good port job, and you get a good tune to help with drivability, than it should run like hell.

you said your heads were reworked. What other than the valve job was done? Any porting? Are the lift specs you have with the cam for 1.6 rr or with 1.5 cause i heard attempting to go over .600 lift especially with stock heads might cause problems. With pretty much stock heads that cam will be useless for your motor especially if you want to use an air gap intake. My air gap chokes the motor a lot more than the stocker but i use it because it was free and my stocker was destroyed in a porting accident. It that cam would prolly be better suited for a 383 or bigger.
