Many people consider that the bigport head is better for high power
applications, and it is not difficult to bump the compression up with a
set of pistons. A good porting job will allow more air into the engine
and a decent set of headers will help get the exhaust out.

See this is the conflicting thing I’m seeing. On one side people say the small port is to small to make big power and that the large port is actually to large. I’ve seen a lot of people going to small port to then get it ported and polished to get it bigger and saying that’s the way which I find almost counter productive.

Other side

Big port isn’t big enough and needs to be ported and polished to enable good power figures.

Even when talking to people and companies that have done NA power builds with good numbers as an end result with good low-mid torque and power band, there option as well as parts used is different to one and other. It’s a bloody minefield!

I’m going to reach out to some of the rally community and see what they have been doing. I’ll also have a look at that like on my break!

Cheers all
