Bill Blydenstein is a 76 year old semi retired man.!
He doesn't fit heads but a local garage will carry out the work and set up on rolling road.
I received an info pack off him jus the other day.
"In some cases an exchange may be made available where a cylinder head, usually from Blydenstein stock can be prepared to the specification req' by the customer (mainly vauxhall or ford 8v heads). Provided enough notice is given the work will take up to two days.
In most cases where exchange heads are not available, the modification work will need to be carried out on the customers own cylinder head. This will take from 5-7 days. again ample notice (2-3 weeks) will be needed to plan work in advance.
Wilsher garages, in conjunction with peter baldwin, can also offer rolling road test/tuning service once the head and any other work req' has been carried out.
Typical charges (to be negotiated respectivly), in each case:
Blydenstein engineering - from £460 to £640 for 16v 4 cylinder inc VAT.
Wilsher garages - From £410 to £590 inc VAT, PLUS gaskets etc
Rolling road from £60 per hour.
Bill Blydenstein - 01736 272866
John Wilsher - 01223 207266
Peter Baldwin ( rolling road) - 01223 207217
Hope this helps you. Best bet is to speak with Bill, excellent bloke and knows his stuff, he will send you an info pack with details of himself, work, and an example of an engine (relevant to you 20xe) which he has modified showing power figures etc, Aslo a price list and all of the above info.
I had a head done by Bill Blydenstein last year, sent off a head I brought off my mate and he got it pressure tested and stuff then did the work to it, It was back with me within a week. Certainly knows his stuff and is a decent bloke to talk to. Noticed a lot of difference when i put the head on. Really did fly. Sold the head to Mark Beeson (Blue 16v Nova) a few months ago when I brought a calibra turbo engine. Speak to bill he'll be able to sort you out.
Wilshers are possiably the biggest rip off merchants in england! they charge the earth and take forever to do the work, unless youve know em for years. It would be better to get the head and take it to paul bailey (who is just down the road from bill) or even the bassingbourne garage, since they are very very good peep there.
It took me about 14 hours to do head swap. That included
fitting new valves and grinding out inlet ports to match the manifold. Oh and a few trips to the tool shop to buy the correct cutting discs for the Dremel thing.
So a garage could do it in, say 8 hours, at £30 per hour that'd be
£250 sort of area.
Add in gaskets, bolts, oil etc.
iF YOU ARE GOING TO FIT A BLYDENSTEIN HEAD I RECOMEND A B+ PACK. IT IS THE TOP DOG WITH MASSIVE IMPROVEMENTS THROUGH OUT THE REV RANGE. I MY SELF HAVE FITTED ONE TO MY 8V. ITS ONLY A 1.6 BUT COMBINED WITH OTHER ENGINE MODS SHE GIVES 16Vers A RUN FOR THEIR MONEY. O.K ITS EXPENSIVE BUT WELL WORTH IT!
I agree with what your saying Mark, but the B+ for the 16V is about £850. By the time i've bought this and payed for fitting i'd probably have been better off saving more money and going for TB's, hmmmm.....
thinks to himself, then goes to look at thr SBD website
You get what you pay for. Plus the head is the most important part of the tuning chain. Stick TBs on an engine with a decent head and you'll gain even more.
And it's about quality - the B+ head on my 8v has made the engine run much more smoothly.
But if you're just after BHP per pound then TBs might be the way forward.
