FYI they say they port match them to the Fel-Pro 1200 but if you actually line them up against the gasket you will see that there is still a lot of meat left . Also out the box unported aluminum heads flow as well as some ported iorns so imo you should at least go through them and clean them up to make it even worth wild to be runing aluminum heads. Also as for the intake u have 3 options. 1 stock , 2 champion, full custom intake.
