Just enquiring whether anyone is is going to use one of the SPA X Flow heads?
If I pick up another mk1 I'd like get one and build a crazy 8v with crazy high compression and ITBs. It looks promising to me.. I'd be willing/want to give one a shot.
Ive bought one and i can understand a little regarding valve strength but im going to convert mine to 7mm stem valves due to i wont be using funny fuels,really big lift cam or high revs and quality of valves available i dont think it will be a problem for my application.Ive got to say im impressed with the quality of casting and overall finish.
I'm considering buying the Spa head.
Any reviews of this head? I'm really really curious at first hand impressions/ numbers/ results.
Unfortunately it's out of stock at the moment, hopefully they got a new batch ready soon.
