Right..

Currently building a Zetec turbo motor, already got new silvertop bottom end and head, forged rods, wossner forged pistons, standard silvertop head with updated springs, now I've jus come into possession of a focus RS head inc cams?

Should I stick with silvertop head an stock 2.0 cams, or silvertop head with frs cams? Or should I use the frs head complete? Can this be done? I'm not changing the bottom end to blacktop because mine was brand new an it's been bored to 86mm now an breathers drilled etc so don't wanna pay again!

Cheers..

 

Id probably use the whole rs head. But then again the grey 400+ BHP mk1 rs in this months fast ford runs a standard 1.8 inlet cam as it give him more torque lower down the revs he says
