Ok i got the heades today finally, they are definately 325/330 type and just a simple bolt on.
The quality is exceptional no cracks and it's perfect. I am waiting on the ceramic paint to arrive, probably in 2 weeks i will ceramic coat them and then install them.

At the same moment i started fabricating a custom cold air intake heat shield, i will post a more detailed topic separately in another topic with bunch of photos. For the moment i am painting it black with a 800 celsius resistant degree paint. I have ordered K&N RC-4630 to match it with my shield. The shield came out great with the hep of a CNC Machine.
