All W2 heads have offset rockers correct ? And noticed some W2 heads look like they have 4 bolt holes on exh ports is this so LA headers can bolt up or ???
Thanks Chris.

All W2 heads have offset intake rocker arms. Not all W2 heads have offset rockers shafts. W2 Econo heads have 4 bolt holes on the exhaust ports. Yes you can use LA headers on the Econo heads but they will block off some of the port. They used to make adaptor plates but I have not seen them in years.

Thank you Sir
Trying to learn about them
Why do some have extra bolt holes where headers go ??

Just curious I just a new set for my Eddy heads or non W2 set ups so was wondering if those can work on W2 heads
I know that intakes and pipes are specific to W2 in general.

Yea they will bolt on. I have hogged out LA headers to mate the ports when I raced with W2 heads. Just don't go to far and it will be harder then hell to tighten up a couple of the outer tube bolts because they will be so close to the pipe.

Should have told ya
I have a 66 model Dart thats my project
The dual exhaust bolt holes are for ether W2 headers or the normal regular LA headers. Exhaust manifolds will also bolt up, but the port mis match is crazy. It still works fine. The exhaust isn’t as important or sensitive to bad port matching.
Most W2 head pipes are large as the head can flow a lot of air in and out, some tubes can be greater than 2 inches. Hedman makes the “Hustle Header” for the W2. They may also still have the adapter flanges. While it helps bolt up standard headers, there isn’t a huge gain in the ports flowing better, or much better. It does improve but.....

It does improve but
let me guess bolts are a PITA
turns out intakes do not make a lot of difference on 360 police cars for example, who'd a thought...

i wonder if anyone has ever done a dyno test comparing the output difference between LA and W2 headers on a W2 head? It would be interesting to see just what it would be if that was the only thing changed.
Depends on the build for sure.
