I have a set of vortecs that i want to port and install bigger valves. my question is should i do all the port and bowl work first and then have the bigger valve job done. Im assuming that after the seats are cut larger Im gonna have to do a little work under the seats to transition them into the bowl. i have read allot of info on this topic but does any one have any more tips on where or what to port. I will be mostly following the article that was is Car Craft about this topic.
