i had a call from someone building a sensible fast road pinto, not a big buck build only stuff thats really worth while, following stuff on the forum he had a skimmed injection head multi angle seats with the inlets cut to suit 1.8 valves, ex valves were std size but rimflow design.
my only job was to blend the seats into the unported head, but a quick look and feel of the inlets with a finger and i thought it might actually flow quite well even though no porting work had been done, first stage was dig out and flow test an un molested injection head, then the modified one, then a bit of blending
