How did you all port your stock throttle bodys to 52mm, did you have a template to trace from ? How did you do it!

do not try to port your tbody! it has to be exact round and the blades have to be replaced w/52mm ones. there's lots of company's that will do it for less then $150 I believe. you can use the stock tbody gasket to match the holes in your new tbody to the holes in the intake. do a search on here for intake porting or the like and you'll find some pics and directions.
