I cannot be specific until Mikael says I can, after all he is a major sponsor of mine. He asked me not to publish the numbers at this time I can be general and say it outflows just about anything out there for the single port as well as split port stuff. Yes I am getting new springs. I would never do any engine building that did not include new springs. That is just good sense and add insurance!!!
You are right stangin99 these are not just BV heads but special ported heads I am the Guinea Pig. The first to have these heads on a car . Mikael contacted me a while back asking me to be the guinea pig on these new heads he has been developing. Mikael, Robert and I discussed my stage RGR stage 3 intakes and these new heads. needless to say I am impressed with not only what mikeal has said but that Robert agreed with mikael these will be impressive.
So I am really stoked about this :headbang: :headbang: :headbang:
