I think these head are good because they give good compression, good flow,and good verlosity maybe better all round than the 4V head ,but lknow nothing not a mm

@@roberthirshfield3571 I do not own a flow bench to do any testing. I will however do some mark to mark times in my car before I install these heads onto my engine. I’ll install these heads and do the same. I will video both tests and put the videos on the channel in the coming weeks.

@ well done Robert. You’ll be really happy with the result. The set of 302 heads on my car I ported a couple of years back, made a marked difference once I’d ported them. Noticeable increase in torque.
