High compression cylinder head BIDALOT for MBK 51 liquid Ø39mm av10

Here is the high-compression cylinder head BIDALOT for MBK 51 liquid engines (AV10). This cylinder head was initially scheduled for the high engines G2 RR (Racing Replica). However you can ask with another high engine and even the origin (careful anyway to squish, at the corner of calotage piston ...). This bolt is very good, it has a tapered high compression chamber polished finish and comes with central gasket!
