Ok that's good then that the rods don't have to be bushed, I take the big ends are fine and just require the correct size bearing to bolt straight onto crank journals including mains (no line boring required) yes mine pulls right off idle right upto max rpm with no hesitation or flat spots and plugs look pretty good colour considering it's a bit rich but the rollers adjusted it to a happy medium if he leaned off topend then bottom and mid were lean so he went for richer top end as it wouldn't be there all the time, maybe mine would make over 200 if it was leaner top end but then bottom and mid would suffer, often think about going to carb as jetting it would give a better fuel ratio throughout, I don't have the knowhow and patience to be experimenting with the k jet as you
( compression doesn't have to be that high as the 285 cam despite it's name only runs 276 duration so 9.5/10-1 should be more than adequate.
