Hello,

I have some questions on porting the e88 head from my 240z.

To give you some context I live in Germany so buying a cylinder head that flows better wont be an option and I wont hand this work over to a Professional 😄

This will be my first time porting a car head but I have ported 2 stroke cylinders countless times.

My first question is: do I really need to remove the valves to port the runners or is it ok if I clean everything exceptionally well after the fact?

I am also wondering what/how much meterial to remove (besides the port matching).

The car is prabably getting a hotter cam a bit more compression and eventually triple 45mm weber carbs

Thanks in advance and greetings from Germany.

Elias
