1.7 heads lack the better port design and lack the better spark plug angle. BUT a 1911 with 1.7 heads with 2.0 sized valves will STILL be fun.

BUT a 1911 with 1.7 heads with 2.0 sized valves will STILL be fun. yes, but i think then i'd be flipping on my objective to build reliable/h.p. when i repair the dropped seat, no more. i think the more i look into it the more i should just rebuild a set of 1.7 heads and one piston/cylander, maybe new rings -most of which i should have. i at first thought 93mm with 2.0 heads, no case mod. just r&r. not much luck yet on that. mike |
