RWD SR20 advice/opinions wanted: VVL head stuck to stock bottom end

[speedingmofa]

Hi guys, I need y'alls opinions as I'm uncertain which route to go for.
I was first thinkin about building a bullet proof block with forged internals, ACLs and ARPs along with a sr16ve head aiming for 450whp with great response. But as its quite a costly build, not to mention the amount of transmissions i'm goin to go through, and it'll probably take me 2 to 3 yrs to come up with funds from time to time. I was wondering what I could do with a stock bottom end + sr16ve head, as the ve head plus practically everything needed for the swap (20V cas, relocation plates, VE oil pump) are already on its way...

So what do yall think? Is this a bad idea? Hows the stock bottom end gonna hold up? I remember a while back Mazworx also build one of their turbo vvls with a completely stock bottom end which netted 491whp. The car then returned to its owner to never be heard of again....
