    what do you think of the fully ported iron ram heads from hughes engines for $1700 plus springs that flow nearly 300cfm. Do these look any good to you guys. I know I need pushrods and rockers but is there anything else that I would need.

    But he still is comparing a out of the box eddy head to w2 pocket ported race head. Sure 30hp is alot but he is switching from a $1300 head to a probably $2000 modified head with a $1000 rocker sytem on it.

    But you say 3 tenths with a pocket ported w2 vs. a unported edelbrock. W2 flow more than edelbrocks out of the box and they have porting. So it is like comparing a ported head to a stock head. Or apples to oranges or a race head, to street head.

    what do you guys think the of the indy/edelbrock heads that are $2500 for the kit. Are they modified enough to support the kind of power I want.

    I will probably go with a set of ported edelbrocks either ported by me or by hughes engines. And get springs that match the solid roller cam.

    but where can I buy econo w2s. I have looked on summit but they just have standard w2s. Also it would be alot more work need special intake rockers and headers. Which I don't really want to do.
