jaas garage vs toda racing japan

i sold almost everything from my race car except the engine and coilovers. the engine was laying in the floor
of the mezzanine for about 7months. due to the difficulty of selling this engine, i thought to flow the cylinder head, which was worked by Toda Racing in Japan.  I sent it 3 years ago, when i knew nothing ( still learning every day) about cylinder heads, flows and the physics involved in this world.

i was very curious about how it will perform against my cylinder head designs. worked hard friday night to
strip down my engine . Got a little surprise with a marked cylinder wall. great for an engine with less than 1000km !

the worked cylinder head from japan, flowed just¨8CFM more than a stock cylinder head.  just 8CFM more.
