Are these any good for a cosworth head i'm going to be running around 540 bhp will these bolts do the job

 

most of the cossie owners will say no ....long stud is the way to go properly or use oe ones and reduce power..hope it helps..

 

Do not use them.....

You cannot long stud a 205 block.
There are a few running around that power with std headbolts.

 

It's a 200 block

 

I still would not use them. There are many threads on the escort cosworth forum regarding them.

Cossie head has 17thou of expansion and contraction in use hence why cosworth and ford used stretch type bolts. ARP do not stretch and can and will loosen over time.

Hope this helps.

 

My mates just had his 200 block long studded. I think that's the way to go
