Juts browsing sites like Burtonpower etc looking at the cost of cosworth tuning etc and came accross the Cylinder head section on Burtons website.

This

CNC MACHINING FOR COSWORTH YB TURBO

Other Info: PRICE FOR MACHINING CUSTOMER SUPPLIED BARE HEAD ONLY ON STD VALVE SIZES.

£1094....

Just for that doing? Surely not?

I was thinking to have a head pressure checked and maybe skimmed, then new valve guides and seats recut you were looking at around the 500 quid mark?

thats why i never buy anything from burton mugoff, had my 2wd head skimmed and pressure tested for 70 quid a few months back not sure about the rest

Lee Reynolds

Yeah ive had loads of work done on CVH engines at my local machine shop for nothing like that kinda money!!

steveboyslim

A YB head is far more work than a cvh head, twice the number of valves (throat) and ports.
Depends what you get for the money, most YB heads will need at least new exhaust valve guides.

i think burton port and polish them for that price as well as pressure test, skim etc...

Lee Reynolds

Yeah i know steve, but surely not that much more work in £££££££

Lee Reynolds

Maybe its a bad advert then? As it puts me off, whereas if they listed all they did you might think it seemed a good price?

SCS/NMS/MARK SHED/ an a few others are good when it comes to head work on YBD

i only say i think mate as like you say its bloody dear otherwise, round my way its £25 pressure test £25 skim £80 plus cost of guides for fitting guides and lapping

Lee Reynolds

Thats more like it mate!

Another thing. At what stage of tune does headwork become needed?

botters

iTrader: (2)

i think its only really neccesary for 400bhp and above but it does have benefits for lesser powered cars as well it can give a more responsive engine at any power level so really its personal preference i suppose

I've seen with my own eyes what a £25 skim does to a cossie head.

AVOID

Lee Reynolds

Cheers mate

Lee Reynolds

Jake, I'd never scrimp on anything mate! The machiners local to me though have been there since my Dad was a lad and before and are still going today Says something to me! I'd go there, i as just wondering where the amount comes from

ask anyone in preston or surrounding areas if they know dave blackburn and then you wont be avoiding a £25 skim trust me the guy is the dogs bollocks ive never known anyone be so meticulous or have so much knowledge about engines, you ask him any question about any engine and he answers you there and then quoting part numbers and everything all of the top of his head, ive used him for 13 years and in that time never had a problem, a comeback or heard a bad word said against him

Lee Reynolds

cant beat reputation and experience mate

Lee,

Mine made 411 at the wheels on a standard ported head. If you are prepared to actually use a turbo for what its designed for, then there is no need for head porting unless you want really high figures. Cam choice is just as important

as said earlier on by someone nick waples is the man for yb heads
spot on and second to none in terms of quality

stu21t

Read the front page and that will b enough to use him

http://www.roperdevelopments.co.uk/index.htm

neil roper, ex formula 1 engineer specialising in head work and helped develop the rs200
and half the price of burton.
He did mine and I'm happy with it.

is the burton add not suggesting that it is just to machine the head to standard condition, ie supplied to them in bare cast condition?

Brett Simms Motorsport does some stormng heads, based in the new forest, really recommend him

Lee Reynolds

Cheers for info lads

The man!

True there is no NEED at lower levels but even on a bog std cossie engine, can make a world of difference to driveabilty throughout the complete rpm range, for not much money.
The man I use has been doing these 54 years, with verified results on flow rig and engine, and chassis dyno's.
If I only had £300 to spend on engine stuff I'd do the mild porting(as I did) the cossie head is a absolute disaster flow wise, way too shrouded amd small ports.
