tsr pack A???

[Mikester]

TSR do good work, i would use them if it wasnt for the price to be honest.

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.

Reseating valves is a right pain!

Hi Ya Ess-Three,

You mention there are better heads in the thread, where can i find these?

You'd need to go to the specialists, asking for a specific thing...
Mine was done by Bill Blydenstein...who has sadly passed away since.

The TSR heads and others done by the same person, are good...on a standard engine with mild / standard cams.
But to get bigger gains, you need to have more work done - and that starts getting expensive!

Never saw a 16v rolling roaded, 8v would add a little but not much.

I doubt it will on a standard 16v either...
The standard head will flow what standard cams need...so no real gain.
Put some lairy cams in though, and you need a head capable of flowing more...so the gains are bigger.

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.

Bill Blydenstein! Wow!
He did a lot of work on Vauxhalls and the race Firenza droop snoot!

Yup, he did my Nova head/engine back in 1995 too!
I kept in contact and asked him if he'd do a one-off ABF and silly VR6 head for me...which he did.

He did articles in Custom Car way back on head work. Things like using a pipette to take water out of the head combustion chamber to measure the volume!

Most head specialists do that, David Vizard and Richard Longman both did the same when building Mini engines.

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.
