Hey guys,

I have a 68 Camaro with a basically stock 454 .30 over, Flat top pistons and stock heads Mild Hyd Flat tappet Cam, Edelbrock AirGap intake and Holley 4150- 750Cfm DP carb as well as a MSD Ignition and long tube headers.

It has 12 bolt posi 373 gear and a M21 Muncie 4 Speed.

Car runs good but just seems torquey but lazy.... I think a good set of heads would really wake this motor up!

Since it has flat pistons and stock heads I think I prolly get a head with a small cc maybe 110? that will bump compression up a bit...

All I'm doing with this is cruise and jump on it ocassionally and rev limter is set at 5800RPM

Do I need to buy the best heads or are some of these cheaper heads fine for what I want...? Or do I still need to pay 2200.00 for Edelbrock or Trickflow...etc

Like these on EBay:
Big Block BBC Chevy 300cc Oval Port Aluminum Heads Assembled BBC Oval 272 | eBay

Is Anyone running Procomp Heads? any issues?

here is the Head Edelbrock recommened... but pricey

Edelbrock Performer RPM 454-O High-Compression Cylinder Heads 60439 - Free Shipping on Orders Over $99 at Summit Racing


Any Head Suggestions?

And whatkind of HP should I expect out of a head upgreade? I was hoping to be high 400s or even 500? is that achievable with my set up?

Thanks

 

For a street car, I'd stay with oval port.


I'd stay with 2.19/1.88 valves since it is a mild motor.


Edelbrock makes nice heads, stay away from Pro Comp, heard too many horror stories about them, check out Pro Maxx, we were looking to use them on a 496 build, good price and good reviews.


Just remember, most of these head require longer head bolts, so make sure you get them as well.


Taking weight off the front by going to aluminum will help you get some more power.
