Reading a russian car magazine I was in the motorsport section, and there was an article about russian ice-ring racing.

Basically this is rather tuned cars racing around a track covered in snow/ice.

Well it was about modified Volgas (pretty big huge cars).

Anyway, it said that the rules stated that the cars must use the stock cylinder head/block (but could be bored), so the cars would be bored from 92 to 94mm and they used BMW 5 series pistons.


What really got my attention is that it said that they do not use a head gasket!!! They simply bolted the head onto the block to reduce a chance of a gasket blow-out (or something like that, I dunno how to translate it precisely. basically something with the gasket blowing or burning).

Also I would assume this raises the compression ratio a bit?

Any ideas on this? (dont intend on doing it just wanted to share this)

yup, dragsters use this method too and it works but es extreemly expensive as u have to get the face on the head and block extreemly flat to liek a glass finish!

some racers ususly use little rings inset into the bores and that all, means you get a better seal so long as faces or perfect.
