Hi, I'm still looking at putting a modern engine into my car. I've been doing a lot of reading on the internet, but can't come up with an answer to this one: how much of a benefit it there to porting L92-style heads??? The L92 heads come from the factory on LY6 engines. So if I get one of those, would I be better off spending my money on a stroker kit and get the cubes up to 408? Or should I go traditional and have port/bowl work done to the heads? Does anyone have any personal experience with this one?
