I had my cobra torn apart this winter due to low compression in #5 and #6, also found all the exhaust valves were toasted and had small damage to the seats, Its being put back together now and hopefully it will be done in the next week or so, in the process I wanted to upgrade things while I was in there also so I am curious what you think ill make this time, im keeping the boost the same until I break in the new engine some. I made 568/535 with 15* timing @19.5lbs with the lower compression, previous mods in sig. Im also going to be running 92 oct with some torco mixed in, ill run e85 once I have some more miles on the engine.
