another awesome thread . this will be very interesting to see how the BM heads will perform I would be disappointed with anything less than 580 hp if I spent the cash to buy them .
This will be super interesting for sure. I haven't been this interested since the first time I ran my W2's. The money I spent on these and the rockers with the exchange was dear to say the least. Ain't no way this build will make 580HP but I agree with you. J.Rob
