ive just done the same swap and was thinking there was a rad problem, i didnt bleed the rad though, just filled it from top engine hose and header and expansion, ran it hot and just kept filling the header. the guage needle is in a different place but its a different motor? as long as its steady i dont care, the rurn hose from the rad stays cold for a long time so i will probably bleed the rad at some stage,
