ok, after spending nearly 45 minutes on the phone with Matt over at Kotzur racing today, im gonna take the head down to them to have the port/polish and machining done. im now debating between the Esslinger 2277 and the Boport 2.1 cam's. i have much more confidence in their work than my local shop, ad he specializes in the 2.3's. with a complete magnaflux, teardown, port and polish, machining, installation and testing its going to be at about $1500. a bit more than i wanted to spend right now, but if your gonna do it, better do it right the first time. going to measure the cylinders this weekend and inspect the pistons more thoroughly, then order the re-ring kit and most likely an oil pump. while im in there i may as well replace it.
