6 Port Head Swap

[Rustyscrew]

How many people are swapping to 6 port head? And how direct of a swap is it? Not that I'm looking to do that swap now but just curious for the potential future.

Yikes, unless you are going big power and studding the head that would be a PITA.

I assume the 6 port makes more power but I don't know that anyone has been able to confirm that. (Can someone with experience chime in? Tunners maybe?)

Prob not many doing it.. unless you're making well over 1,000whp it's a waste.

Not worth the money or hassle

It can be done but will be expensive

What is expensive about it? They do bolt right up (I've seen them both off in the same shop), Are you referring to just sourcing the 6 port head?

The cylinder head is a separate part but expensive itself plus hours of labor to guarantee proper installation.

Oh - I was assuming if you were one of those in the camp where the extra ports on the head were necessary for your power goals you'd be doing the work yourself. I can't even begin to imagine someone else doing a head swap on one of my cars. ha.

Much more common for cars to be built by a shop these days than by the owner but of course if you have the knowledge to work on these motors yourself it would be cost effective

For the cost you may be better off trading in for a 2021.

Before we get too far away from 2020 and 2021 cars being low mileage and stock, I really wish we could get a '20 and '21 owner together on the same dyno, in the same conditions, and do some pulls to see truly what difference exists in power being put to the ground in stock form. Anyone know of a situation where this has been done? I can find stock pulls for both, but never at the same time, same dyno, same conditions, There's always some caveat, like one person has X minor mod or X was done 6 hours later when it was 20 degrees cooler.

Hell, I'd even gladly pay for the dyno time if someone could hook it up.

The advertised wheel hp(s) that have been out for year are accurate.

Just the part is like 4Gs+
