Either way, I don't think you're gonna have too much of an issue with your heads, running decent size cams (272's mate, DO IT).. make sure you port and polish!
Like I said, Sean runs MY98 WRX heads, and Tino runs STi ("small port") heads, albeit modified. They both have big boost and big power, so I don't think you're gonna have a problem with them.

Yes i started off with small port heads but theyve been enlarged considerably so i
would not use this as a valid comparison..
Seans runs big boost though so also take that into consideration...
Big boost makes power albeit not efficently... just ask rigolis... they dont care about head work..
