if i was you i would steer clear from jonspeed! (from personal experience). there are plenty of good engine builders out there just depends on what budget you got and what you want in the end.
If you make a statement like that can you give your reasons why please.

the head i brought from them was ground too deep into the chambers which caused it to crack on the inside and seep.
i went to them as they were cheap, there cheap for a reason!
it was about 5 years ago now but ive learnt my lesson, id rather got to the like of morspeed, med, or swiftune and pay ££££'s reather than going chep and getting rubbish!

med quaily engineering and ok prices
swiftune THE BEST but probably one of the dearest but for a good reason, nick knows his stuff!
my current engine is 50/50 med and swiftune!
simon at morspeed used to work for med so hes knows his stuff too
theres others like sh engineering, skip tune but havent used them
and one you carnt find easy is parker power used ex autograss racer and knows his minis i brouht the clubman im racing from him

basically i brought a crank which was x drilled knife edged wedge and ni tempered which got fitted to my race engine in the second heat at racing i was still running the engine in when suddenly the engine went bang! what had happened was they x drilled it BUT only drilled one extra hole (instead of two) then they grub srewed it but went too deep and blocked the oil way all together causing is to wear the shells out and because it got so hot locked the engine up and the flywheel turned on the crank which was then scrap (ulta light steel billet). the old man i spoke to said i didnt know what i was talking about when i rang him to tell him so i went down to his shop and chucked it on the bench and tell me what was wrong which hey presto he apolagized and made me a proper one.

Things like that happen anywhere when you are machining the life out of parts for racing

I have not purchased an engine from mini speed but I have purchased a cylinder head and I had no issues with it and the service was fantastic. a friend of mine purchased an engine from them and he has had it two years not had any problems.
another option is to go for a second hand engine from a company named MINI technique they helped me with a problem I had for MOT

Asked for it to be black. It turned up red with an awful paint job! it was a stage 3 998 head and the work was good and gave a good power increase (although i never had it on a rolling road).
I complained and got a free sportex exhaust so it wasn't all bad!
Just tell them not to let the apprentice paint it....

However, the head he did was very nice for the money. I personally wouldn't go back, but if you only want a straighforward build, you'll get what you pay for.
