These heads claim 40 HP over stock......will they give that?

Ebay Heads

 

i thought i had a magazine and vortec heads flowed like 240-250ish stock on the intake side which is pretty good. They would probably add that much but they don't fit LT1's so it doesn't really matter.

 

Ditto.

 

Opps, I missed that.....damn! thanks!

 

Correct me if I'm wrong but aren't the valves on those heads the same as the LT4 heads anyway? Are the LT4's 1.94" and 1.55"?

 

Hehehe
I know what you were thinking. Since we look for LT1 heads when we are in the market esep on the FS section, anything we see, we automaticaly in our heads assume/think they are for our LT1

 

What about these I know he doesn't have flow #s, but they look pretty good.....how much HP could these give me?

 

Jeebus he couldn't even spell camaro anywhere near correct. I would find out who did the port work, and more details about what parts he used to rebuild. Buy used heads off E-bay is a high-risk deal usually.

 

what about these ? Or, some guy is selling some heads. Here are his descriptions:

"The LT1 heads flow 260/235 cfm (int/exh) and the lt4's will do 295/245 cfm. The LT4 head will go a bit over 300cfm with a 2.02 intake valve. The numbers above are with 2.00 int and 1.56 exh."

How much will I gain from each?

 

ebay freak eh?
I would NEVER spend that much without a FULL flow chart/sheet.
You never know, b/c they'll list the highest number but the flow numbers could tail off and start declining, and thats very important to see...

 

I'm just looking to get some head, I mean some heads......
