I have a set of fresh from the Machine Shop (Modular head shop) Stage 2 POWER ADDER heads. Specifically meant for a roots application. I need a set of NA heads. These have oversized stainless valves and bronze guides.
$1000 cash, will consider trades for low mileage stock PI heads or NA heads. I can't pull of the blower any time soon so I need to get something I can use.

Nice talking to you, sorry these won't work in your application. To be clear for everyone else these have been cc'd specifically for power adder use.

A couple people have asked and to be clear on this issue, no I will not trade even for stock OEM heads. I have over $1000 invested in these at a great deal.I need at the minimum $650 to take STOCK heads in trade and they need to be ready to install at that price. The more they cost me to get fixed the more I need to get in trade.
These heads are worth $1200-$1500 easily plus cores.

Allen what's the power adder part mean? Are they too large of a combustion chamber or something? Need more info.

They were cc'd to decrease compression ratio, if you want to run them on an na car you will have to throw mass timing at them.

I'm not sure exactly, I didn't have it done or do it so it is hard to say. I bought them that way and sent them out for bronze guides and to be ported properly.I'm guessing maybe 45-46CC combustions chambers. I don't have anything to measure them with.

If you take them up to Matt, he can cc them real quick for ya, be easier to sell. Heck they may not be that big, who knows?

The swirl dams have been removed which is why they are best suited for a power adder application. If they still had the swirl dams I would run them myself. I guess I could run them with increased ignition timing, but I really am not making enough power for these.
Still have the heads. Need to get my car going.
