go for it, a p+p head will give gains in any car

plus that means turbo valve springs get that rev limiter raised you will need a new cyristal for the ecu I think 13,900 to take it up

hi

thanks guys for the replies but i already gathered that a bit of P& P will be of benefit . i was more interested in what the differences in C/R`s are between the 2 heads & any othe variables

i have a set of V/springs &billet c/shafts i was going to fit to my STD head , but will fit to this head instead if it can be proved to be a worthwhile up-grade

DO NOT FIT the springs if they are speedvision ones mate! speedvision cams are fine but with cruise springs, speedvision springs cause a world of shit due to base pressure being to high causing premature wear on the cam lobs as well as other issues
