new engine purchased- head / exhaust question

I decided to add another 100hp to my blazer and purchased this engine. My question is... will I need new exhaust manifolds because this engine has vortec heads? I have 2.5" ram horns now, will they work with the different heads? I have a crate 350 in there now, but it has the original style heads.

I used ram horn manifolds on my crate engine with vortec heads with no problems
