Excellent quality!
I used these adaptor plates to put an LS3 Magnuson Supercharger on a set of LS2 243 heads. Initially it looks like things wont line up, but after you torque everything down it lines up perfectly, I verified the port alignment with a scope. Great value,

Works as described once you have the correct bolts
This did work as needed to adapt a ls3 intake to a cathedral port head. But I have to order longer bolts from ICT billet

Perfect to convert my build over to an ls3 intake

Ok part needs modification
Had to modify these to fit a stock ls3 manifold then had to trim the manifold to make them fit. It is a good product and everything ict I have gotten has been great. These just require a bit of timing and modification to work.

Works great , port match needs a little work but gets the job done.
Excellent quality , Machine work is like everything else Ict billet offers . The port match could be better but nothing that can’t be cleaned up with a die grinder .
