The head has 33.?mm inlets and 29.?mm exhausts
Firstly am I correct in thinking that these engines were MG Metro so they already have a decent camshaft as standard?
Secondly, shall I change to a 1.5:1 ratio rocker assy.
Lastly, rather than buy a new head should I just have the inlets opened out and replaced with 35.? mm ones and do some head porting and smoothing.
Is that likely to get me 80bhp
