Major build up weld work - project to increase flow -ai

Dear all
As some of you know my 382 on ITBs is now on the road and ready to race.
What I am planning is a rework of the manifold as the power band is a little lower then I would like. The manifold is quite a restriction - and although it's making great power I think I am loosing about 80hp as the peak HP is at 800-1000 rpm down on where it should be.
Peter Knoght has seen this problem before. My plan is to do some serious porting on the manifold! But need a significant amount of bud up weld on all the runners to make it work.
Post weld machining will be done by my mate Richard Campbell - so not worried about a "bit of warping" (less the better obviously.
Does anybody know a good alloy welder?? Or is anybody here interested in the work???
Cheers
Dave
