Unless it is an all out effort engine (big compression, big cam, 700+ HP etc) I'd do -2's

Just out of curiousity, what kind of block will you be running and what's your horsepower target?

You can get that from ported eddy magnum heads for alot less...chevy type rockers, Indy intake bolts on...

Hummmm....
Let me rephrase this, I'm shooting for 10.5 at the
track.
Are we still on the same beat with the Eddy's ?

I would go with the indy heads, makes it much easier to reach your goal with room to grow. eddy heads your about maxed out. how heavy is your car?

yes they re full race ported by Dwayne. it's a comp 308R-262@.050 575/575 a really mild cam. ran right at 130mph in the 1/4. only draw back with the fully ported one with small cubes is the lack of air speed on the off idle hit. you could probably reach your goals with out a full porting and higher compression and a bigger cam. but like they said it can be done with eddys just not a lot of room to grow. you would have to change heads if you wanted to go faster.

Compare cost and then make your decision. Indy is great, but really you don't want their rockers and their valves don't add much to the flow of these heads...so by the time you upgrade it aint cheap.
But hey if you gots the $$$ then yeah Indy is great way to go.
If you go with the 210 head you could always get it ported more later if you needed it which would cost you less than changing from the eddy heads to the Indy's.
Just have to figure out what YOU want...

Id buy them bare and make them how I wanted them. It is TOO expensive to buy heads right for your combination today just to rebuy everything tomorrow because you want to go faster and youve already outgrown them. Id say to the OP, if his car has gotten increasingly faster over the years, Its likely he has the et chaser bug. Buy bigger, buy once. If you can swing it.
