Is the price you spend on ported iron cheaper than new aluminum heads (plus machine shop inspection?) and what would be the flow comparison? If that could be known. And is the flow from the iron heads enough and/or worth it to you vs the cost of aluminum heads?

Hey do not find anything wrong with iron heads.

Thing is I already have both, I have flow numbers close to my cam max lift in my first post and its 277 iron and 301 alu @.600 lift. These are not the same flow bench numbers.
They are close but I simply have these alu heads and am tempted to try them out. Plenty of winter time ahead with some time to wrench on the car...
