The manifold was marked out & cut parallel to the flange
The angled half was marked out parallel then ground flat, both halves were chamfered
Each join was filed perfectly flat & the 2 outer faces checked to be parallel
The two halves were clamped then TIG welded, this gives a neater weld with more controled penetration. The face mating to the head was then checked for flattness & lapped to suit. Ready to go!!!!
