The head's coming off my NB8A this week/weekend to have for a bit of a freshen up & a shave . Anyone know how much i should have taken off to get the CR up a bit on the stock 9.5:1 - I'm thinking 20thou should get me close to 10:1....
Cheers,
T

IIRC 25 thou is 0.5:1 so 20thou will be pretty close.

Thanks Babs!
As I'm not going for cam gears yet, do you reckon 25thou will throw the timing (or anything else) out too much?
Thx again,
Tony

It does retard the timing a touch I think maybe 2 degrees. But that's alright...more top end

Thanks again Babs... Hope to have the head off tonight/tomorrow and back on the road in a week or two...
