I recently bought a hx35 off a 24 valve and it has the external wastegate. Whats the best thing to do to these to make a little more boost? It's going on a first gen cummins with stock head bolts I got the head resurfaced and new gasket so I think it will handle pretty good boost. Whats better the banks big head or just plugging the wastegate hole?
