I am currently doing up a late FIA head. It is costing a lot to do up but it will be worth it. I had to sell the last FIA head I had due to extreme poverty. I will try to not repeat that mistake. A cost breakdown is: - $100 testing for porosity, cracks and hardness. $300 inc freight for hardening the head back to T6 specs. 214N stainless billet valves tuftrided tuliped and swirl polished are $528. Valve spring pairs with matched rates $280 a set. New silchrome valve seats and new bronze guides with 5 cut angles on the seats and the radius blended into the chambers and face machining back cylinder face and manifold face $650. Flow matching of inlet ports and flow matching exhaust ports to ensure 80% flow of inlets $600. 8 new rocker arms (lightened and polished) $240 + time to modify. Machining cam tower for flow modifications and to fit cam spray bar $100. Billet "Clive Cams" camshaft $210. Titanium valve spring retainers $240.
Total costs for the head will be approx $3200, plus manifold gasket manufacture ($300) and fabricated extractors $600 - $1000?). This is on top of the purchase price for the head in the first place. Any wonder you see the heads and inlet manifold only on Nissan Sport sites in the US for $3400 US. It costs money to do this stuff properly and you get what you pay for! An FIA is a bit like owning a works 510 SSS safari car vs the 510 deluxe granny car. Both are great in their own right, but one is a lot more fun and appreciates greatly in value. Other heads may be better (OS GIKEN or LZ16 valvers) but this head was available and they arent :-) A mint L18 OS GIKEN head went back to Japan a while back. It sold for Y 1,000,000 $14,450 AUD) with all manifolds, carbs and cams.
