im getting diff information from diff people on how much to remove from the head.................2mm seems a good bet???...the blitz site says 1.6 for 9-1...i need 10-1 really

im going to be using a ''race'' copper gasket from nanni.

all the info i have is for the 650 head not panda.........

i think ill risk it for biscuit and go for 2mm.......might have to pocket the pistons but thats cool............ :cool:

Go for 2mm. It will be fine. I didn't have to do pocketing with 3mm head but it also depends on sive of the valves, how deep valve seats are and of cours on the camshaft.

Remeber that you can always take off more :twisted:

up date,i was introduced to a gentleman engineer today,he worked for weslake cars when they were building the eagle weslake V12 F1 cars in the 60's he actually was one of the engine builders/developers working for Harry Weslake...........he has offered to cut and reface the head and match and relieve my inlet /exhuast porting for me..............also to lighten my flywheel..................................

has also given me an original eagle weslake transfer that was fitted to the nose of the f1 cars..........i am just not worthy................

update.....head back with helicoils fitted to plug holes,and 2mm off the face......... valves lapped in,ports cleaned and matched to elbows,all cleaned and first polish done,final polishing with brasso this weekend....... :smt028

have you got a dremel ? if not get one they are ideal for getting little polishing jobs done . dont use brasso or any of that sort of stuff get yourself some polishing soap (blue for your ally head) . polishing is my favourite pastime , which is very very sad......

126dave · « **Reply #24 on:** May 12, 2007, 09:00:19 AM »

have a dremil mick,and first polish was with fine lapping compound/cutting paste,its all shiny,but brasso gets it perfect without affecting the ally....and i havint any blue

126dave · « **Reply #25 on:** May 13, 2007, 07:53:02 PM »

all done,ports polished to a shine.......elbows ground out and polished as well..........all bolted up with copper gaskets and stainless fittings.....and valve's/ springs etc all refitted with new oil control seals......

an ideal sunday methinks.... :smt028

sounds like a good days work Dave, just one question how the hell do you get the nylon valve spring oil seals on. when i tried i ended up flatening them so i ended up putting the old nylon ones back on,

hi pete,i never did find the correct panda ones.......god knows where to get them......i fittted 850 ones....black rubber with a steel insert at the bottom and spring at the top,very tight to fit,i made a small tool from an old ''tophat'' wheelchair wheel bearing and used that to tap them on gently.

Pete126 · « **Reply #28 on:** May 14, 2007, 07:56:09 PM »

never had any trouble with the black rubber ones with the spring clips but the white nylon ones that came with the h/g set thats another story.

my panda head did come with white nylon ones,with an outside circlip,i searched every where for them,in the end a guy from the fiat uk site offered some early panda ones,(not 850,sorry),he used the rest of the gasket set for 850 rebuileds and had these over....they are the closest i could find.and seem to be ok.....panda 30 parts seem very hard to find,as does info on the cam/dizzy used etc......got to be more to that 30bhp than carb and head?
