help or advice changing cylinder head

[steveaddy]

hi all wondered if anybody could give me and tips or advice.i am slowly trying to repair my wifes 1.1.pug 206 04 plate the cambelt slipped a while ago and damaged the head. i bought a replacement head from ebay which had been reconditioned.i stripped the damaged head off and the valves had been damaged and slighlty marked the pistons. the replacement head i got was from a 2002 pug 206 1.1 and was told by the man i bought it off who said was a mechanic it would fit. ive since put the new head on and all mates up with the block fine but has a slight defference to the old head as the inlet manifold is different, i have got one that will fit from the scrapyard it looks different to the one i had on it is a more square style and connections are in different places i think i have figured what goes where apart from one connecter that has a diffrent end so i think i am just going to swap the connection over so it fits it the plug.the 2nd problem i have is the cambelt sprocket on the new head is bigger than my old one.dose this make a diffrence?it has a larger bolf holding it on so i am not sure if i can swap it for my the one on my old head? as when i went to pull the cambelt over the sprocket it will not go.i know pug do 2 belts one slightly larger with a few more teeth so could i just get the bigger belt?any help would be fantastic and i hope one day to get this car started and out of my garage
thanks steve
