New Summit vortec heads
I was looking at the new summit book and came accros new vortec heads made by summit part# SUM-151124
I was wondering if they are worth the price because I am in the middle of a vortec head swap.

www.competitionproducts.com sells pro-topline "vortec style" heads with screw-in studs, and springs good to .510" lift for $499.
You may want to check them out too.

The following link has flow numbers for most of those heads, the stock GM vortecs dust them all with ease, I'm assuming the Pro-Toplines would do the same. Would be interesting to see some independent numbers for the Summit and Pro Topline Vortecs though (not on the list I don't believe)
Scroll down to the bottom for the links to the seperate sections. http://www.carcraft.com/techarticles/41598/index.html

If these heads are actually the same as Toplines I can say I know someone running them and they seem to flow slightly better. I know of two people runing the stocks and the Toplines and the Topline car traps slightly faster so I would say they flow a bit better.
