porting round head to square?

[e_racer1999]

i have an N47 L28 and i was wondering if anyone knows if i can port the exhaust to be square? i know it's going to be a lot of work, but i don't want to have to get headers for the N47 head (with round ports) and i don't want to have to go through the valve work with my E88 head.

basically, i want to port match the head to a set of square port headers because the round port headers i found aren't as nice as the square port ones... anyway, thanks for the help!

Get yourself an N42 instead, it's identical to the N47 except it already has the square ports.

i'll do that if i can find someone that wants to trade for my N47, otherwise i'm el broke-o....

so basically what i'm trying to ask is "is it possible to port the N47 to have square ports without MAJOR troubles?"

I think your going to get pretty close to the water jacket. Unless you do most of the porting within the last 1/2 inch or so.

Are you going to race the car? If so what you're wanting to do is important on a performance basis.

If it is a street car, you can just bolt the square port up and go.

If you measure the round opening I believe you will find that the square port opening is equal or larger. Square can bolt to round but not round to square.

Good luck.

i plan on racing it later on, but not in the near future... i still have to disassemble my L28 and i still have to order my headers.... thanks for the info!
