tsr pack A???

Yea but as that was like over 30 years ago it was news to me at that time! Also showed you where to take metal out etc. etc.

To be honest, I was looking at around 16 years ago myself when I had my Mini engine built.

Any head work that will be done on my VR will be done at local trusted places, plus i have heard that porting a VR head is almost pointless for the gains, so i will be just uprating valve springs, and have it all reseated etc.

You have heard wrong...
You can get good gains from a VR6 head - again, along with cams.
I saw 30+ BHP from a friends VR6 with a properly re-worked head (Big valves) and Schrick 268 cams....and the engine is awesome.

Not all the gains are from the head, of course...but not all from the cams either...but do both...and the gains are there.

Sorry, i was meaning that what i have heard is that you dont get much from having the head ported on a VR6. Although if i had the money, i would have bigger valves dropped in for sure.

TSR for a pack c head, with bigger valves etc you are looking mega bucks.

I'd hope you'd see atleast 30BHP from a VR. The ported head has decreased BHP dramtically!

Don't think you can get bigger valves in to be honest.

(I will stand corrected if wrong)

 VR6 12v Pack 'C' (only for 2.8 engine)

We are able to fit 2mm larger valves in the twelve-valve VR6 head, resulting in vastly improved flow and subsequent power and torque gains, especially when fitted to a 2.9 litre engine.
This head also gives excellent results from the 2.8 litre engine without having to resort to a bottom end rebuild or other costly engine work.
To gain even more benefit, we advise a gas flowed throttle body (£295.00) be included in your budget.

I wonder then if the 2.9 has bigger valves as standard.

[Mikester]

Apparently the heads are the same on 2.8 and 2.9, or thats what i read on vr6 oc i think. Although might have read it wrong.

Just wondered why they say only for the 2.8.

The Blydenstein head I had has 3mm larger inlet valves and 2mm larger exhaust valves.
The gas flowed TB you can do yourself with a Dremell and save £295!

I don't think you get much on a standard engine...but that's the same with every engine.
Standard cams, TB, etc are all designed to work with the strandard head...bolting on a head that can flow lots more, doesn't mean it will flow lots more...you need the cams as well.
Do both, and see big gains.

Same on a 16v...
