Fantastic head in it's day,but a U67 head will out flow them now and has a better combustion chamber when modified correctly.

Would be awesome but if you think about it you can buy a decent old dato for that price and have it built with an SR for that! |

Port size is not everything That is an early FIA head with the iron cam towers. Ports were too big on these head and on the later FIA heads with alloy cam towers the port size was reduced with better results. I agree, ported u67 heads would probably make more power these days |

When i toured nissans facilities in 79 I had access to the works dept. As i was leaving with a heap of gear, including a new FIA head, I noticed a guy porting a head in a sealed glass room. Asked my guide if i could enter, your pass ok he said. Porting heads was my forte , so was super interested to see what was being done. He was porting an FIA head ( the early one like in the pic.). Heaps coming out of the exhaust ports. I watched for while as he finished roughing out, and I had seen what i wanted, I asked why is he porting a new FIA head. The guide asked the mech & the answer was . : The factory always must have advantage over privateer. So guess what I did? BTW both early & late FIA heads ( had a few) Measured intake ports were the same. main difference was early had 45mm inlet valves 35 exhaust & late ( smaller  ) 44mm, but larger exhaust 36mm.I found the torque under the cam with the ported erly head was very good. When on transport stages or driving in traffic, i would shift 1 3 5, skipping 2 & 3. When you have a 2.3 first & 1:1 fifth the massive ports & 48 webers come into their own. Competitive stages would never see you under 6K in any gear. My max effort & best L series race heads were done on new 200B LPG heads. 40mm intakes for customers heads & 41.5 for my own. The bigger ports were a bit iffy & if I stuffed up , it was my own fault. My favourite was the FIA head,and still is, they just needed porting. |

The U20 head was the precursor to rhe FIA L head. Many similarities. The U20 was an expensive engine to produce. Standard U20 on Solex carbs made 150 HP With development, 245 HP, in an Australan prpared SR311 model race car, still racing today, 45 years after first being raced. Stock L series were more cost efficient, hence their large numbers and long production use |

This is an old thread now, but I have an early model FIA head so it came up in a search. So Baz, what Nissan facility did you tour in 1979, that sounds exciting!As i was leaving with a heap of gear, including a new FIA head, I noticed a guy porting a head in a sealed glass room… Jeff |
