Has anyone used these?

I think my oil in coolant issue is down to the head lifting under full boost. When I rebuilt my engine a few years back the only bolts I could find were Victor Reinz ones. I've since discovered they aren't really suitable for over 350bhp? So has anyone used these Anembo bolts with around 380 bhp and ~32psi of peak boost?

Can't comment on their head bolts but had all sorts off them and always been of the highest quality

Cheers! Hopefully their bolts are the answer to my problems.

Have you got a metal head gasket on there? Mark Shead always recommends them over a certain horsepower

Have you tried BGA head bolts..i had same issues with Victor Reinz ones..this ones no problem at all..plus the head gasket with rings from Navalinea motorsport works very well..

Yeah they do last much longer than the fibre gaskets, group A gasket on mine only last 10k miles.

I had a new 200 wire rung block, a group A spec ported and polished head with a group A head gasket fitted 19 years ago, 2bar of boost, done over 55,000 miles and still going strong.Never blown the head gasket despite the car getting regular thrashing so what are you doing to blow a group A head gasket in 10,000 miles?

Yours has been wire rung

It is a rather unlikely cause of water/oil mixing although possible. What oil cooler is fitted ?
