Match this 500hp/500lb-ft Combo?

In these types of threads I try to approach it from the viewpoint of someone who doesn’t have the skills or equipment to do the job themselves ...... so they’re going to be “buying” heads.

I also don’t like to look at it through the lens of being able to score a “deal” on some used stuff.

I like to recommend something that anyone would be able to come up with....... or that 100 people could duplicate.

If the thread starts out with, “I’m going to port my own heads......”, that’s a different story.
Agreed, most times I figure people don’t have an extra 2-3K to really spend on ether big heads or porting.
...Called being a wise ***.
Like you said, many ways to do it.
Rhs heads made an easy 500hp with hyd flat in the 286's duration around .500 on 4" combos for years @.270cfm and 180cc
Not in line with how the Oe poster asked the question but I do agree. That would also make for a nice track engine in a light car. I figure that “286” is an advertised number.
Uuuhh..... no.

One of the better “deals” for ported iron heads would be from Dave at KG engines.
He’s got a cnc program that supposedly gets them into the 280 range.
Yea? No ****. Someone actually CNC’a iron heads.
Huh, learned something new today.
Does he have a web site?
