hi all, got the head picked up today, not as clean as i thought it was goin to be but any more and he'd have too sand blast it which is a lot more work & money so not really bothered, the remaning isn't loose so it'll be ok and he hasn't charged me for it. it also went through the pressure test ok with no problems.

he's checked the run out of the valves and cleaned it all as it came apart and its all ok which is good.

this is what it was like last week:

and now:

he lapped the valves back in today too check they was seating ok and all is good and springs are returning ok.

is this (area in red) were the paste has been on the seat? so don't touch that when porting & polishing?

so the main question is how do i go about porting & polishing it? do i do the whole tunnel? as much info on this the better, please! dunno..

here the cams that i want to send to PIPER but not yet spoke to them, there website states astra/vx220 but will they do the vectra ones?

they all look good (only roller marks)

as above, as much help, info & comments the better. i'm learning every day doing this so please post your views & input.

thanks nick
