2005 Infiniti G35 coupe with 6MT. I currently have nothing done to it but a rebuild coming soon
Best Cylinder Head for Rebuild

Hello all Im new to this forum and I currently own a 2005 Infiniti G35 coupe with a 6MT. Im gonna be rebuilding my engine soon and as you can tell my the name Im curious what to do to the heads to get good power out of. Im currently gonna be working to get Wiseco pistons with a 8.8:1 ratio and Eagle connecting rods. Ive herd from other owners that installing the 370 HR heads are a good combo but Im trying to get ideas at the moment. So if any of you guys have some advice or recommendations it would be greatly appreciated. Thanks guys!

I'm not familliar with that at all, typically head upgrades involve a radius cut valve job, different cams, heavy duty springs, titanium keepers, and porting. Anything more than that are you're getting into oversized valves and the price tag shoots up astronomically.

I've never heard of someone using entirely different heads on the rev-up, you would need the timing chain equipment and covers to fit and I don't think they do?

Maybe I'm wrong, I'm sure someone will post the correction if so.

Are you sure you're not thinking about the HR gasket on the rev-up block which is a common and recommended upgrade if you have it all apart.

Yes Iím positive itís swapping the HR heads but I could be mistaken as far as if itís the 350HR or 370HR but I know a couple people who have said itís a good combo
