I picked up a used set of Gen 3 heads to port.
Intake valves are 1.99-2.00 diameter (not stock size???)
Exhaust are 1.58
Stems are .310
I haven't CC the chambers yet but I need the stock size.
Also I can see the 3 angle valve job.
No porting was done, all casting marks/imperfections in the ports are still there.
Thanks in advance.
