up date well today in the cold i install the new head, new intake i torque the head in three stages ., 25 50 80 pound by the torque spec. i torque the intake at 30 pound. attention i think my risers gaskets is wrong. i dont have a restrector what i see is all open slot gaskets. the system is raw water cool. am putting it back together with the open slot sits on top off the manifold then the spacer, on top off the spacer i now put the restrictor gasket the riser now sits on that, is that the correct way guys. i always notise the manifold runs hot but the riser cool to the touch. now i fill both manifold with acetone i did not notice any drips in exhaust passage, i let it sits over night , result one manifold still has a lot off the acetone but the other side was almost empty , both manifold look great but scared one might have a problem. ow well . your thought guy,
