head gasket change has commenced

well the head gasket change has commenced today whilst waiting for me socket set to arrive....i have a question though for those in the know......i set the timing as per a websites guide to the job ...took the belt off...but as i was removing the top pullies it seemed to jump round about quarter turn......can i expect issues when im putting it back together as regard to timing? or will it sort of come together when i line the marks up again? cheers

K series laser cam locking tool £5

Secondly know correct way to fit cam pulley's

You shouldn't have any problems when you put it back together just line the timing marks up on the cam sprockets, as already been said use the laser cam locking tool.

cams are already off chaps..but im asumeing i just line up marks....il knock a clamp up in the garage tomorrow.....put that on and then re build?
