this is my first attempt at doing this. i have case matched an e50, portmatched exhausts and intakes, never messed with any cylinder wall ports tho. i am well versed in dremel tech, small files. i plan to widen the exhaust up to 1mm on both sides and raise it up 1mm as well. i have been reading the books in the wiki. kinda like muffin shaped exhaust port. i may also try and make some transfer eyebrows.
any tips? eyebrows a good idea? who done this b4?
