I am also adding a downpipe, water injection, and a stahl. Would porting and polishing the head and intake do much for hp to make it worth the extra money. It cost $500 for stage one and $1000 for stage two on the head work but with the other upgrades I dont know what to expect for hp out of it. I was also thinking of buying a cam, there is a stage 2 cam for about $500 and stage 3 for $1000 with new springs and such to handle the rpm. Is it worth it? I don't want to put much more into it because it is already costing about 6k!

The last thing you want to do is cheap out on quality because your too cheap. Do it right the first time.

You don't need to upgrade internals if your only going for 500 ish hp. Make sure to get a good tune out of it, otherwise you'll have problems. Don't bother with cams...a head upgrade definitely wouldnt hurt you though (valves and springs, etc, whatevers in the Ferrea package). Porting is ALWAYS a good thing, but don't port the lower intake manifold too much, it'll mess with the fuel vapor.

Note: bolts are much easier because with studs you have to put the head on with cams out because the studs are too close to the cams to start the nuts. Although studs are proven to be better. As far as porting and polishing can't help you there. Cometic is a PROVEN company though. check them out

Eesh. Don't stick to any one company, number one. MHG is definitely the way to do (metal head gasket). Do head studs (again, don't cheap on quality because your lazy), they will hold much better.

Agreed. Studs are much better. And no you don't have to stick to any one company a MHG is just the way to go. I've learned the hard way on a rushing a project and cheaping out. The second time around I took my time and money and did it right. I would highly suggest doing that the first time as it will save you MORE money in the long run
