hi, tabatha, thanks for the reply!
the mk1 xr2 is a 1600 though, and i personally know of a few mk1 fiesta 1.3's (supersports) running twin 40's (dcnf's and dcoe's) allbeit crossflow engines not valencia's like mine all been cammed though to cope.
and even a cammed 1.1 mk1 fez running twin 36dcnf's all run ok.. but i dont know anyone with a 1.3 valencia engine and which cams were most commonly put in them????

appreciate any advice or info
