yes jimbo cams will be on the way , to be fair we was only going for 480bhp @ 27/28 psi and it was me saying to your old man fuck it stick some more boost in that we did over 500 bhp , i probably would of gone for a little more tbh if the duty cycle on the injectors was at 90% lol.
i know its each and everyone to there own but ian is my engine builder and iam sure it was fit for the power we needed (480 bhp) and if theres room for improvement it will be made.
tbh ive never heard of spark plug issues apart from you saying which i believe as scs is a great company and have probably dynod more zetec turbo than anyone else.
the only problem i had was on my first head which had modified plug holes to accept cossie plugs and kept having misfires due to the plugs sitting in the head slightly lower thus not allowing the plug leads to clip on the plugs properly and unclipping themselves .

i take it you mean lee at devil uses m12 bolts

and no ian howell is shut but still helping loyal customers


cheers paul
