Web Cams 294 regrind, Need help with this. Options

[bdawgbp1]

I just got 2 used cams from a 5S and am going to send them to Web Cams to get the 294 regrind done. I am running a basic modified 5S-FE in my 94 GT (CAI with K&N, 4-1 race header, Nology Hotwires, Pulstar plugs, and am fixing to have full header-back exhaust done next week - 2.5" or maybe even 3" for future boost). I was wandering what do I need to do with my stock head for the 294 regrind? I have been reading in the forums and have seen stuff about the valve shims, clearance, etc. I originally had intentions to buy a new/rebuilt head but didn't know if there would still be some additional work that would need to be done to it for the 294 setup. Any help would be greatly appreciated as this is my first "tuner" that I have done - pretty much done this sort of thing with '70 to '80 something model V8s before but the Toyota is another whole different ballgame. Thanks!

its basicly a timing belt job + more work.

you have to reshim all the valves for the new cams.

i like to measure the shims before you install the cams, install them, check clearances, then figure out what size shims you need to make up the diffrence.

i suggest doing the 1ZZ FE shimmless bucket conversion. alot of supra guys report spitting out shimms with 272 cams. plus the 1ZZ buckets are 30% lighter

will the 1ZZ buckets fit in our heads?

these cams are very mild, no need to worry about spitting shims with them.

So....I'm planning on doing a 294 grind on my 5sfe. I'm confused if there's anything I need to do with the buckets/shims or will it be fine just leaving it stock as is? Also the valve springs. Do I have to upgrade the valve springs or the stocks are fine? Please. Don't answer if you haven't done it yourself.

I'm planning on replacing the valve stem seals though.
