Welcome Greg.  Glad to have you here. 

I was wondering if you'd share a secret and (even PM?) me the percentage improvement in flow from a change to larger Intake valves and seats?

On a Gen 2 head when we go from stock 1.920" valves to 2.02" valve and porting we gain about 70 cfm. IIRC the first heads we did with stock size valves would get to about 280 cfm. So there is about a 30 cfm gain going up .080" in intake valve diameter on a Gen 2.

On the Gen 3's the intake valves I put in are 2.02", which is only .020" bigger than stcok, which is 2.00". I have done a few sets of Gen 3's with 2.100" valves.

So "stock" is around 240 then?  No wonder they have such a broad power band...

That's a great looking intake manifold above!

Thanks Greg,

I try to keep up on head technology.  The answer I was expecting was about 10%, so a little more does indicate that it's a "good" way to spend money.   :goodjob:

Thanks

John Beck here in Houston built the intake. I've always had great results from his work.
