The estimation for the Nismo head is ~$25k for just the head, not sure if that price included the valve train as well... Derrick's head is ballpark the same cost.

There is one more company in japan JMC,that is making heads as well, they have a recast of the N42 heads w/ better machining. https://party-k.co.jp/used/index-3536.html

I have a 260z with round-top SUs from my 240z with L26, its not bad, it's a single click to get that engine running, even after sitting for a long time.

On the carb setup, I find the fuel smell to be a bit overwhelming, to the point where I don't want to drive the car as much because the passengers reek of fuel when they get out. I cant even run a shitty CAT on the exhaust because it would get destroyed by the carb. This is probably also due to leaks in the body gaskets...

I think it's really just the turbo that I want, I cant get smoked by these civics :(

if you already have a carbed zed then why not! the block is bulletproof I bet it takes the turbo like a champ.
