I am trying to decide what parts to use to build a stronger 1975 1800 engine. I just bought a NEW 1800 complete short block for $500 and I am confused about what head to use? Do I stay with the original head and just get it rebuild and add a performance cam, dual 40 Webers, and a free flow exhaust, or do I put on a 2000 head? I know where there is a ported and flowed 2000 head for about $350 and although I was not planning on getting this head, I was not sure if the 1800 and 2000 heads give the same compression and flow. I will take any suggestions. I am new to a Fiat and so far I love it. Since the car will be a daily driver, I have decided to make the engine, suspension, brakes and electrical like new.
