2000 R Heads-Value?

[Twisted2v]

What’s up all? I’m looking at buying a set of pre production R heads, and was wondering what a fair price is to pay? They are complete with cams. Thanks

Not sure if anyone will have any comps for comparison. These would be super rare.

What is different on these pre-production heads vs. production?

I have a set of 00r heads I bought bare, I do not remember the cost, what I do know is the valves are custom, valve springs also have to be custom. The machine shop I worked with did not figure it out correctly so I have a really expensive paper weight at moment. I am thinking of pulling heads and sending to Kassi and having built. I am sure that will be cheap. But I now have so much in motor I could have bought another 00r. Good luck.

The valves are the same as 07-14 Gt500. Stock Gt500 springs or PAC springs work. The real issue is the lash adjusters, half of them are gt500, the other half are unique.

If they’re bare they are a lot less valuable, but I’d say in the 2000 range bare.

Yah, been there, no from my experience not same.

I mean I literally have both sets of heads, and the valve trains for each.

The springs are different, but interchangeably fit the head. The R valves have the part numbers inscribed on them, the FGT/Gt5 does not. Maybe the exhaust valve is a different material, but they are the correct sizes. Now the valves and springs differ from other 4v stuff...
