Porting question

ok thanks. i bought these heads from my buddy. he purchased a 73 challenger with a 12:1 440 that snapped a rod, he sold me the entire motor for 100 bucks and these heads were on it, they deffinately have been ported. only thing that worries me is that when whoever ported them did, they went through the intake runners and epoxied them, what do yall think about that?
first pics are stock 452s vs my ported heads, and the last picture you can see where the ports were epoxied
