i think youd be ok with the bottom end you've got with that setup, you should be able to get half of your standard BHP on standard internals

The 1.2 was Rolling roaded at 59bhp last year thats with just a 4branch thats 4bhp up on standerd. but then again.. we all know what RRs are like..

i think 70bhp is reach-able...

we'll see, you wont get the gains you would of a 1.4 because the head is very restrictive, so when you put a less restrictive head on it increases alot, while the 1.2 has probably the best head

wel am puttin a 1300sr head on with the inlet and exhaust ports matched and i got told the 1300 head would be alot better...

the car its coming of is a 1400 with 1300 head etc and it made 90bhp

its only going be for a year until insurance goes down enuf to put a xe/let in

its not really the head that does it as its the same as the 1.2 you had, but the fact you've got a 1.3 inlet would help as it means you can fit a bigger carb to it, and you may want a 4-2-1 exhaust of a 1.4 as it flows better

Keep with 1200 head, use 1300 inlet. You should see 70bhp easily.
I wouldnt bother with arps for your spec.

Shouldnt need bolts unless your planning on increasing the rev range matey.

7k ish is ok on std bolts.

Which will be plenty of a 32/34.

I dont have arp's fitted on mine, it seen a few off the tacho blasts, and its still running,Lol.
