Hey guys, im just wondering if anyone has a spare ecotec head to measure up for me. Im just after the inlet port sizing if possible. I dont have access to a spare set of heads atm and want to get started on the inlet porting so i dont go to far and then have to do the heads.

Im porting and polishing the inlet manifold atm after the plenum episode. So if anyone has the size of the inlet port on the head could you please let me know? Cheers.
