Do the HKS head gaskets instead of the Nismo's. They will seal better with the stopper rings.
Tomei cams will not work with the Rev-up heads with magnetic valve timing.

few things to mention
1. the stock heads have a 3 angle valve job already
2. oversized valves - not with only a Tomei 268...I wouldn't bother
3. Tomei 268's are no longer in regular production
4. The NISMO headgaskets are excellent
If you end up striking out with the heads you got, let me know. I have a set of 03 heads I'm selling that will work perfectly for your engine builder to play with and build

Did everybody miss this little query?
Short answer: No.
Long answer: do a search for 300 hp and see what you find. It is the golden nugget of N/A builders - only a couple of people I've seen have attained 300 whp, and that's with a fully built engine and lots of tuning.
