I am currently running the TR 224/112lsa cam on stock heads with Hooker LT's. I have been reading along with you guys opinions, it seems that all the sponsors here make some good heads for this cam. Do each different port job create power in certain areas of the power band, if there is such a thing as heads better for "low-mid", "top end" etc? What would you recomend for this cam?

Also, I am running stock tuning right now, with the addition of heads, would I definetly need tuning? My idle isn't too bad right now but I didn't know if the heads would worsen the idle?

And the other important thing, is it smart to go with dual springs with the new heads?
Thanks, amigo's!
