40's

[-Greg-]

i dont know if they are 40s or 45s would both fit?
greg

[Stuart]

in all fairness theya re msot likely to be 40's and yes they will fit with the Sr inlet manifold..... or fit the SRI head and use his existing manifold

[-Greg-]

ok cheers what if i fit a 1.2 head as ive herd that that will give you more power as i have a 1.2 engine sat in my garage?

[Stuart]

an sri head will give more power than the 1.2 head.
and you would still need a different inlet manifold for the 1.2 head

[-Greg-]

so will the sri head be a straight swap with mine, what inlet would i need for the 1.2 head and would the 1.2 head make a difference in performance from mine standerd 1.4 head?
greg

[Stuart]

inlet for the 1.2 is the 1200/1300 one.

the 1200 head will be better than the std 1400sr head.

[-Greg-]

ok thanks for that but why is the 1.2 head better than the 1.4
greg

[Stuart]

the 1400 sr head is a square port type which is very restrictive and not very well flowing. whereas the 1200 carb head has good flow comparatively

ok thanks
