Well, to completely honest with you bro, the diffrence between the flow characteristics of the GSR and SiR heads are minimal....maybe almost non-existant. But IMO, spending more hard earned $ on a GSR head for your application just doesn't make any sence. You can pick up an SiR head for about half the price and have the exact same performance (maybe even better in some cases) than the GSR. Here is a link of some pics of GSR, SiR, And Type R heads so you can see the subtle diffrences between them.

LOL I didn't see the link you posted either. Robert's doing my valve job, and spec'ing my bottom end. Small world.
