rate this stuff for add some horses on a 318

we have to add about 20% for taxes and custom fees - the tricky thing on this one is: the calculaction will be made on the purchase plus shipping fees (so if you like to import a heavy or a large part (with high shipping costs or expensiv airfreight fees) you will pay a lot more than often expected when looking for a part in the states)

I feel your pain Timo, we have the same set-up in the UK only with 20% tax and 5% import duty, also including shipping fees. RHS/Indy iron heads have my name written all over them but those hefty shipping costs will be a double whammy!

Like the look of the combo. My 318 has 2.02/1.60 valves in the stock heads which is overkill for those little ports but now I'm going 390, so new heads it is! You may also struggle matching the ports to the RPM intake.
