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.
I looked into this just for curiosity and it appears that there needs a lot of machining for them to work. I does not appear ready to bolt on and go. I'm not a cross flow person but if I was, I certainly would look into this.
Don't these require custom intake and exhaust manifolds?
And what kind of flow numbers are they going to give over a ported ABA head?
I doubt it would be worth the money, unless you were running forced induction.
