Headwork - Vic?

spope · 22-09-2005, 09:26 AM

I posted this initially in the General Tech forum. I might get a response here.
I have an EB 4.0L head here, that I am trying to figure out what to do with.
I am after reccomendations, firstly, for a good place that knows Falcon I6 heads, that can port, polish, etc - preferably with a flow bench.
Also, what should I do with it? I'm thinking XR valves (if there is a size difference) and springs, port, polish.
The engine will definately be staying N/A, turbo is out of the question, I will be rebuilding it soon with an ACL race series kit with flat top pistons, using an AU headgasket, etc - looking to get much higher compression.
I will probably stick with the EF cam for a while, as aftermarket computer management is not really an option for some time, so I can't put too lumpy a cam in there - unless someone has a good combo reccomendation (billet, not regrind - i don't want to shim anything)
If anyone can point me in the right direction, I'd appreciate it.

I'm not really sure where you can get headwork I'm still trying to decide myself. For what you want I'd reccomend a jim mock dev5 cam, even though they are a regrind theres nothing wrong with using shims. The dev5 cam seems really good big power and still idles good with stock ecu.

Hey Steve, I don't want to pollute your thread.. But just a quick question; getting headwork for an N/A engine.... is there a compromise for having good power N/A and then being able to use the same head for a turbo application without any issues?

Well with an N/A setup you typically want fairly high compression, with a turbo setup you want lower compression... for a compromise I guess you would keep it as stock compression

neb: Got it in one. Part of doing the headwork would be to get a little shaved off as well. To lower the compression though you could either fabricate a decompression plate, or use multiple headgaskets. In terms of flow and valve sizing, there shouldn't be too much difference.
LTDHO - yup, dellboy pointed me to the thread. $170 for a reco - i've PMed them.

You want Engine and Headwork, no problems.

Give Michael at Head Tech Performance / Cylinder Head Re-conditioning in Williamstown a call 9397 0525 Or drop pass there.

PM me for more details.

Currently they are building up an EL Falcon XR6 5spd manual to Turbo plus engines rebuild and an EL Falcon Futura to a N/A rocket as well as an X series GT into a Turbo.
