That amount of lift is already pushing the stock head clearance so if you want 1.6 rockers with that you'll definitely have to get your heads modified to accept that kind of lift. If the 1.6 rockers don't clear the covers then you can always modify the covers which isn't a real tough process.

 

what mods would the stock heads need... anyhting big?

 

ok iv read about some stuff and i think the 1.6 rr are to much lift but is that true. if i ut them on with my cam will i brack somthing or gust be close to pushing it to the edge. my cam is .465 int and .465 exh. is that to big for the 1.6 on stock heads. should i seand them back and get 1.5 or is my cam almost to big for a 305 already
