Heys guys, Im planning to do a head gasket on my ea soon and i was just wondering what experiences people have had in regards to machinging of the head....do a lot or a little, i have manual, exctrators, exhaust...should a little head work give me a noticable power gain??? and what is the averege price or abouts for headwork both standard and for extra work???
Cheers

From what I've seen, I think most people would recommend simply using a later model head, than working the EA's (probably cheaper and better result).

Try a bit of a search about the place on I6 head work, your bound to find lots of interesting threads. . .

Thanks

wouldn't putting a 4 litre head on a 3.9 lower the compression an in fact adversly effect performance? I guess the larger ports etc would offset this but wouldn't better gains be had from getting work done to the 3.9 head instead if you weer using the 3.9 litre block???

apparently EA heads are the worst of the e-series. Why not get a later model head and work that? I've had my EA head worked by SVO for 800 bux. It will give you a power gain but to get the most out of it you really need a cam. Just get a Wade regrind for 150 bux or whatever they are and chuck that in at the same time.

Does the ef head bolt staright on??? I need to do a head gasket also, wat gaskets would be best?? AU? top of line EA? Is there any other mods that need be in order to fit an ef head.....im on a budget and i just want a little bit more pull not an all out machine!!!

Yeah the EF head bolts straight on, I've put one on my 3.9L. I used an EF/EL had gasket, and you'll also need an EF/EL rocker cover too, otherwise it'll leak badly.

Thanks Goodz....What price will i be looking foe a ef/el head?? are they readily avaliable or will it take a bit of hunting??

would there be any gain in fitting a std ef head to a ea bottom end? same compression ratios arnt they?
