So, this is what I got

440ci LS, currently has an older set of 245CC Cathedral Port ETP Heads

So, I was thinking about going to a 275cc set of MAST Heads, still Cathedral, since I already have the MAST Intake

Trying to pick the performance up, is it worth the coin?

Or, what heads would you use?

Just gathering opinions here.....

What about having your 245s opened up to a 275?? What's the intake valve on your 245s??
