I will have feedback on these shortly , I have taken a bunch of pix & ported them already just need time to post it all
bottom line they are a decent head IMO , the portmatching on the intake side is near perfect out of the box , the porting in the intake side is approx the same size as I port Irons heads to , there is some extra meat arount the intake valve guide whuch can be trimmed but not enough to fully shape the way i do the iron heads , the exhaust port is small , I typically open the iron heads bigger than the stealth heads are but there is lots of room to open them up , the exhaust has minimal floor height with zero excess around the guide to remove or shape , the is virtually no excess flashing or core shift & slight ridges just inside the ports that should be blended
decent head for the $$ , not a lot of port clean up needed , I would like to see a raised exhaust floor , smaller volume heart shaped swirl chamber & 10 * locks & retaineers used
I will try to get this set onto a flow bench soon to see what the flow is like
