SR head

[zeifer33]

Hi, I have problems with my 1.4SR engine. One of the valve is broken and I want to ask if I can install the 1.3SR head. or better mod.

1.4 head will have the naff square port inlets.

best off getting another 1.3 head or a 1.2 CARB (not SPI as they are the same as 1.4's) head.

You can use the 1.4 se head it has bigger valves and better ports but there is a problem it has round inlet ports and you'll need a manifold to mach.

[Stuart]

which is then a problem as there isnt an off the shelf inlet for a single carb to the 14SE head... (otherwise I'd have suggested that too )

Just slap another valve in.

I have a single GTE head, what do you think you use a nova GTE head, valves, springs, etc with a 14NV cams?

[mowgli]

your problem will come with the inlet manifold/ports not matching....
then the 1.6 combustion chamber is probably bigger, ao the compression will be too low..

Got some valves here, PM if you want one.

Just slap another valve in.

thats what i would do, otherwise you would be faffing around with it for ages,whilst your putting a new valve in relap all the other valves and make sure you get a head skim so you know everything will be perfect

Idealy you should re-cut the valves and seats, then lap the valves in.
Make sure you check the valve guides for wear before you do anything, especially the exhaust ones.
