WELL i'M STARING WITH BABY STEPS, ONLY GO TTHE K&N, RECENTLY INSTALLED THE CC305 AND I'M LOOKING AT 1.7 RR AND MAYBE PORTING THE CYLINDER HEADS, I HEARD THAT 2.02 1.60 WOULD GIVE ME NOTICABLE POWER, WOULD YOU AGREED.???
I'M NEW TO THE PERFORMANCE WORLD AS YOU CAN TELL, BUT HELL IT'S ALOT OF FUN !!!

The 1.7 rr's might be a little too much on top of an aftermarket cam. A set of 1.6 rr's would do the trick though. As for the heads, a port and valve job will unleash a good deal of power. Lloyd Elliot or A.I. both do port work for reasonable prices.
