Stroker or Not

Not IMO because they are prone to cracking, and you'll never get your money back out of them. If you spend 500-600 dollars in just porting alone, which is what it takes to really see a decent gain, you know you'll have way more in them with machine work, parts, etc....now how much will they resale for???? Pennies on the dollar.

That's pretty noteworthy info comming from someone who has a flowbench and gets paid to port heads.
