in the box vortecs
Has any body out there heard of the brand new aluminum vortecs w/68cc chambers? Is there valve lift limit prob w/ these as I have read in other threads? Like 470 My buddy who is an engineer for gm say they will be the bomb for my 383 stroker that is being built as I write, I'm getting close to buying intake & want to know if anyone has had experienced these? They go for $1100 in the jegs I do believe and I got them for 600

The winning magazine engine masters challenge small block a couple of years ago used those heads, reportedly out of the box (the rest of the engine was anything but).
