mods for the head

[pauljones]

Hi all,
Thanks for all the replies,loads of useful intonation to pass on. I think,to keep the price down,I will keep the valves that are in the head whatever they maybe.then get the head ported to suit these. If im right then I should be able to get a good spread of torque,and a good lump of BHP. The cams may need to be changed for a bit bigger lift and a few degrees of extra duration.ill have to look into it but qed 420 spec seems to give good results.
Either way, I have asked for before porting flow chart and after porting flow chart.this should give me the details required for cam specs.
