once it has all been fitted parts only turned up today....
thought it would of been more than that?
is that RWHP?

 

[Buckeye Viper]

420 to 425 at the wheels

Which would be about 500 bhp.

 

[99 R/T 10]

Yes, sorry. RWHP 420-425.

If you are only putting "bigger valves" in stock heads other than springs without any port work unfortunately there is little if anything to be gained.Bigger is not always better especially if the path of flow has not changed.You may want to seriously consider working with the heads before you assemble.

Baz,
The most important work on the heads is in the area just before the guides and down to the seats. If you design that area correctly and still go with stock valves will you notice signinficant power gains. In my opinion is a 2.20 Valve over the top.
You will gain almost nothing on port match, the match is very good from factory. (dont polish)
And...remember that the camshaft is what makes the snake bite...
