Upgraded valve options?
 

Where have you guys purchased your oversized valves from?
Belfab has supertech @ around $17 a piece, FM is $5 more expensive per piece. I've found an ebay seller that is $1 cheaper than belfab but I haven't factored shipping. Anyone find any cheaper?

i would not choose ebay over belfab, fuck ebay man
supertech is what i will be getting once i do a build, many threads here where people talk about them...im sure you'll find a bit of info if you search

www.importperformanceparts.net has all the supertech junk.

course their website has vanished off the face of the earth.

Reference: http://www.importperformanceparts.ne...ves-mazda.html @ $17.50 per

Shoot, I forget where I got mine, they were pretty cheap, I remember that. 'Course, they turned out to be like 0.4mm over, not 1mm over, but whatever - still cheaper than OEM and the stems had a nice grind on them

sorry forthe slight thread drift. Will oversized valves turn your engine into an interference engine if the timing belt breaks

They shouldn't unless you deck the head and block a significant amount.

or run a higher lift cam...

I run SI's.. they were under $200, and they are beautiful!

they look like they have a few different options. but man does their website suck CLICK HERE.
