We never stop on our pursuit to find better performance for the most effective cost and reliability. we have decided to spend some more time on the abarth 1.4 cylinder head but this time on stock valve size.

We have changed the radius and the roof of the port along with the seat dimensions. we have managed a much more efficient port with a much better coefficient of discharge.
thanks to this changes we still have great port speed and manage to no loose any cfm on the lower part of the lift. for sure this will be a great power adder for those looking to get the most of the stock cylinder head without braking the bank.

on v1 head only intake ports have work done

for exhaust port work as well please look at our v2 head porting

we can also offer upgraded valve spring options, please contact us for further options we might have available for these

on pictures you can see the cfm graph and avg flow per lift
