For what i read about your modifications, i had nothing to answer, you have done a lot on the car.... i was going to tell you to change the pistons for the flat ones, and increase the compression ratio, i dont know what else to say because as far as i understood you don´t want to mess whith the block ... mmm if you change the cam, have you changed the rocker arms for lighter arms?, you could increase the revs

P.S. don't get us wrong, the people on this club are really nice, and patient, as you can read english is not my native language and they have the patience to answer me and try to understand what i ask, and i'm not the only one, there are a lot of people from around the world, and newbies with a whole bunch of questions.....
