Head Games?

[ChrisR/T]

So, from the bible thread:

I've got stock Magnum cylinder heads, don't know if they're the HD's or not. Anyway I can check and see if they're the HD heads?

If they're not, is it an ok (not good/great) idea to get stock heads ported? How much do the R/T cores cost? I don't need valves, springs, etc. I have all that stuff. I just need the heads and to get them ported.

I was going to have my stockers ported and throw 1.97 valves in'em.

What does the DRTC think?!

You can get 2.02/1.65 EQ heads for $800, why would you waste your time on the stockers. Unported the EQ's outflow ported R/T 1.92s

[ChrisR/T]

Because I already spent money on stuff. LOLz.

I'd like to know who started that one.

EQ heads have that 318A part number on the intake runner there.

interesting.... and ~$300 diff between them.... guessid better start saving more then.... lol

[mtlcafan79]

Don't forget Eddies drop 50 some lbs off the front end too.

[slvr03dakrt]

eddys all they way. my vote goes to them for ease of porting aluminum (for future upgrades in my case) and the weight savings.

[ChrisR/T]

So, what's the price cost of these heads? 800 for unported 2.02 EQ's, 1100 for Eddy's?

I think I'll have around 700 or so in my ported/decked 1.97 heads....

[mtlcafan79]

Eddy heads are closer to 1,300 and change now.

[ChrisR/T]

Oh wow. :-O

[slvr03dakrt]

yep i got em for around $1355 before the work i had done to them.

[mtlcafan79]

Mine were $625 each before advance auto noticed their pricing error. :D
