I'm looking at buying an FC that a buddy of mine has been working on. He recently rebuilt the engine and decided to expand the ports.

It was originally a GTU but he did the turbo conversion (TI drivetrain / goodies) and had it running that way for a few years. He only recently took it apart for the rebuild and re-assembled it only to find out that he needs some form of EMS for this port job.

I'm curious what you guys think about these ports. Are they shaped decently? He says he deviated a smidgeon from the pineapple template.

You don't need an ems to run a street port on an na.

You can tune the fuel curve with a fuel computer like an safc.
