You might have some issues with bracing bracket lengths, as the long ram manifolds were designed for the RB 413 type block. Also, the cold start-up performance on these manifolds did suffer some. Depending where you are in the UK, you could experience that as well. The 6-pack manifold is a better choice for overall driveability and fuel economy, but I will admit that you cannot beat the long ram for underhood visuals!
