cosworth cam choices
 

Im thinking about getting the standard head ported and polished and changing the cams on the sierra cosworth.
Can anyone recommend a good place to get the porting done...I dont know of any good places in Ireland so I will probably send it to the UK.

Also can anyone advise me on cam choices. Basic engine spec is 1mm overbore, 7.8 CR, cometic head gasket, swedish inlet manifold, T38(possibly upgrading that too)
