sorry, i dont have stock flow numbers, i was in a rush to get my head finished so i could get the motor in my car, i whiped up the fixtures so i could flow it to get data to buy my cams. my boss did the port work and valve job, i did all the guide install,surfacing,clearencing for cams,and assembly. there is stupid amount of work in the head, i converted to shim under bucket wich is alot of work to set up lash.

my boss has been porting heads for 20 years, he has alot of experience with 4 cyl, i can pm you my flow numbers if you like
