evo 8 head rebuild ?

[timmycat]

I am looking to rebuild my head and upgrade my cams. I haven't really messed with any serious engine builds, so this is my first try at it.

What valves, springs etc. should I get? What about cams and cam gears? What else would I need? Where should I shop for the parts?

I am looking for something streetable, but the goal I am shooting for is around 500-550 hp down the road. I am just looking to make the engine as reliable as possible before I slap on the big turbo.

Thanks for any help.

You can make those numbers on stock internals and a good tune. If u choose to do cams i would recommend a set of 272's from either comp or hks. As far as any other head work goes it wouldint really be all that necessary but if u have my mentality on building motors which is build it while its off then by all means do so. If your looking for more power down the road then i would definatley suggest some cnc work on your head and possibly oversizing your valves but if your goal is 500 awhp then IMO i would just do cams.

I would get the GSC or FP beehives and a nice 272 cam like a Kelford/GSC/Cosworth. Cam gears are really more of an appearance thing on a 500 hp engine. I really have not seen many gains over the stock port compared to cnc or handport at that power level, you could clean up the bowl area but that is about it. Stock size valves are fine as well. Your major issue is going to be your power goal. You are on the line for the stock rods. Some cars live for years at that level on stock internals and others will shoot a rod out the block. This is really going to depend on your driving. If you like 1/4 mile runs you are safer on stock block than if you like highway pulls. How many miles are your engine ? you maybe able to just do drop in rods and pistons. Also what "large" turbo do you plan on running? You can hit 500 on a red with E85 and 30 psi or a 42R at 20 psi (or less) on pump gas : )

checkout bushcurs head packages just add cams and your good to rev out way over 8k perfect for the bigger turbos if thats what you want. I like smaller more effiecent turbos that spool fast.
