ejin4499 Posted March 13, 2012 Share Posted March 13, 2012 Hi everyone ! I finally have some money and I am in SERIOUS need of a pair of heads for my 92 pathfinder ! Please help. What happened to your old ones? If they warped you have other problems that need to be fixed first. Link to comment Share on other sites More sharing options...
Tungsten Posted March 14, 2012 Share Posted March 14, 2012 (edited) How much money? What happened to the old heads? Are you looking for replacement heads or better flowing heads to add more power? You can look into a complete engine swap if you want more power. There was only one design change as far as I know in VG30E heads and it wasn't major. The better heads are on the VG33E version of the engine. Edited March 14, 2012 by Tungsten Link to comment Share on other sites More sharing options...
Slartibartfast Posted March 14, 2012 Share Posted March 14, 2012 Save your 30 cams though, aren't the 33 cams smaller? Link to comment Share on other sites More sharing options...
Tungsten Posted March 14, 2012 Share Posted March 14, 2012 Good point. Yes the 3.3 cams are less aggressive than the 3.0 cams. Link to comment Share on other sites More sharing options...
TahoeRunner Posted March 14, 2012 Share Posted March 14, 2012 Trying not to thread jack, but can you just simply swap the VG33 heads onto the vg30 block? Link to comment Share on other sites More sharing options...
Dizer92Pathfinder Posted March 14, 2012 Author Share Posted March 14, 2012 I am looking for replacement heads ! So if i need to rebuild them i can. So i can still drive my pathy.

5523Pathfinder Posted March 14, 2012 Share Posted March 14, 2012 If the heads can be rebuilt, contact your local machine shop and see what the turnaround time is for a complete rebuild for both heads. I have done some in the past and the machine shop at a 1 day turnaround. If you want heads, I would recommend going to a junk yard and pulling a set, have them rebuilt and have ready to install.

Mr.510 Posted March 14, 2012 Share Posted March 14, 2012 I have several sets of heads available, probably at least one set each of the four different casting numbers produced. VG33 heads are sought after, especially by guys building high-boost turbo engines, for their larger 10mm exhaust studs and better intake port shape. The cams are junk compared to VG30 ones so you'd want to swap in your stock cams if you got a set of these heads. What's the casting number on the heads you have now? (It's cast into the outside of the head, just below the valve cover gasket surface in raised writing.) To make it easier to find/decipher, the possibilities are: V52, 21V, 85E, and OWO. Like the others that responded I'm curious why you'd rather buy a set of heads to rebuild rather than sticking with the ones you already have?

Dizer92Pathfinder Posted March 14, 2012 Author Share Posted March 14, 2012 (edited) I dont have the Money right now to purchase Rebuilt heads. Hopefully gonna find out how much OR were to get Heads that are good from? I have a VG30E . It is SOHC. I will try and check for Casting numbers when my Fiance get's back from the grocery store. Thanks everyone! Edited March 14, 2012 by Dizer92Pathfinder Link to comment Share on other sites More sharing options...
Slartibartfast Posted March 15, 2012 Share Posted March 15, 2012 Rebuilt/junkyard picked is probably a whole lot cheaper than new. But, yeah, what's wrong with them? If you can pin down what's wrong, you can buy just the bits you need, install them yourself, and save a whole lot of money. If they're ticking like a sewing machine, that's the lifters... if they're leaking, replace the gaskets... etc. Link to comment Share on other sites More sharing options...
k9sar Posted March 15, 2012 Share Posted March 15, 2012 sounds like he wants to have a set of heads to have rebuilt and ready to swap on. That reduces the "out of service" time for the vehicle if it is the only thing you have available. I have a spare set of sitting in my garage that I kept off my old engine for just that reason. Problem is that I haven't rebuilt them yet Link to comment Share on other sites More sharing options...
