318 head porting for the average joe
Personally, i don't thing you need to get that crazy in the bowl area.(Depending on what your building for) But now that you have, you need to build temples so that you can have the same port(Bowl) shape when you do all the rest of them.
Sharp edges, scrape fuel out of the air stream. So you need to smooth them.
I would ruff up a few more ports and then go back and smooth up your first.
Now build temples for that port, make the rest the same.
Now you have a head, to test on you eng.
Exh., i wouldn't port at all, clean up, leave the floor untouched.
EDIT: Sorry guys, didn't realize this post was so old.
