mrs cezeta complained that her engine was a bit flat compared to mine so ive put a mmw head on for her (and her standard head and spare barrel will get a stage 4 by harry barlow)

the head has made an improvement in its self but before she goes swanning off on it with no tools or jets im wondering if the new head and higher compression will require an upjet due to increased heat and efficient burning.

ive never just changed a head on its own so have never seen the effects on jetting.

any thoughts?
