I have Sean Hyland Stage 1 Heads (99) - does anyone have any idea if the FR500 heads would flow nay better. A signifigant amount? What are the costs of the new heads?

Yes.

The FR500 heads are probably the best heads you can get right now. They run $750/each, bare, so you are looking at $1500 for the pair, plus valvetrain and assembly.

I have a set of FR500 heads being built up right now. The bare heads I got 2nd hand but unused for less than FRP list. To that I have added SHM Stage-2 cams ($750), and ModMax valves and valve springs (~$500). Then a little P&P job by TheGame. Hope to start the headswap in a week or two, then dynotune. When done, I'll post results.

Black that sounds badass, can't wait to hear some #s.

TenSecond, I highly doubt that stock FR500s (which are only supposed to flow ~20% more than 99 heads) will outflow ported 99s...but when you port the FR500s...
