Hi as I've got my head off my cosworth focus gain and I've got all the stuff ready to start putting the head back togever I was think why not use a ARP stud and nut kit . But befor I get one or not I would like to no your forts on them . I'm running 400Bhp on a 205 block 2wd head .

 

Please don't use them. use standard head bolts. Arps will over time crack the block around the water jacket. It happened to me.

Can i ask why the head is off ?

The funny thing I've all ways used standard bolts and I've got a new set now .
Well it's a bit of bad look to why the head is off again as I had had my fill of the anti pump tappets I put in witch are 100% shit . Any way I moved the car to put it into the garage to put some new tappets in well as it's been some time since I had driven it I tuck it for a spin . All good pulled up at home lifted the garage door started putting it in the garage and it cut out and it would not re start
so checked it over and as I'm using pegged pullys well the bolt come lose on the inlet cam and move the timing 180 deg and killed all the inlet valves

 

Oh shit thats bad news.

Use std head bolts you don't want anymore issues.

Question is if the bolt came loose how can it move 180 degrees and the woodruff key would stop the pulley moving or is it the peg is attached to the outer and bolt then came loose?

 

These are the ones I'm using it's 100% my fault that the bolt come lose

 

Sounds a bit of a nightmare, are you using an aftermarket oil cooler aswell as the standard oil modine or is that a remote filter take off?

 

im running the standard oil midine one with a remote oil filter take off witch then runs throw a oil cooler .
But I have been thinking of removing the oil midline and seeing how it goes with out it .

 

Ah i see now. Now that is bad luck.
I would also ditch the oil cooler and tbh it don't even need a modine just a filter like a good old pinto.

Mine runs near that power and torque on std head bolts and a 94k engine. So once sorted it will be fine.

Are you using cams? Or just verniers to get timing spot on due the head skim or block face?

I always use blue loctite on cam sprockets just in case.

 

I try to give this motor as much cooling as pos as it dose a lot of trackdays and a lot of flat out when we do Bedford.
Its running BD10 ex and BD14 inlet cams

 

What oil temp are you seeing after a few laps on track Ian?

 

hi martin long time no speck .
to be onist mate I don't no at this mo in time as I don't have a oil temperature gauge in the car but it's going to one soon
