For what bhp.s is enough to use original cosworth head gasket without any problems?

On the standard head hasket, SOUTHAMTON UNIVERSITY were having to do head gaskets on STANDARD BHP engines when the did the NVH testing for FORD/COSWORTH.
Standard one is not worth having really even with standard power.
A group a one YB 0611 will cope most say up to around the 400bhp mark, and is FIBROUS so a very good one, as it will cope with any slight imperfections in flatness of head/block much better than meatal ones.

In my full gasket set from motorcraft was victor reinz head gasket. Can I use it with no fear for power around 300-350?

At the end of the day a gasket failure isn't a great event, if you have it already I'd just use it. It's not like 300-350 bhp is massive in the scheme of all things Cossie.

Victor Reinz make the oe ford one and the group a.
A std one will not last as long as a group a, if you look very carefully on the end top side you will see it's number faintly printed.
Victor reinz also make a SINGLE PIECE METAL GASKET!!

The number is: YB 1261


it means that I can use it with the 300-350 bhp, mates?

I've seen many cossies running 300+ bhp with std gaskets

imo its a lot of hype gasket failer is mainly due to the early 2wd heads not being that good around the water jacket area...and people drivin cars when they know they have a problem eg leaks overheating etc

And poor fitment surfaces must be spotless and a good quality torque wrench should be used

I personally cannot see any difference between a std and a grp a only the numbers

The number is a std part number.
There are of course different opinions on this subject, only you can decide what you are happy with.
They are made differently, if I could find the letter from V/R I would post it but can't, probably not got anymore.
Southampton UNI had perfect heads blocks etc all with NO MILEAGE, and only 10 minutes on them and they STILL failed.
I do appreciate what COSTINA says and to a large extent it is right, but certainly not all failures are due to this.

bud-weis

the 1261 is a standard small turbo escort cosworth gasket isn't it? in which case it's just as good ( probably better ) then a Grp A 0611

Thanx mates, I ready to install this std and if it failed, that will be the karma of my gybrid scorpio-cosworth!
