is that 1200 with springs,rockers,rods?

Or just a bare head

yes, at www.jdsperformance.com they have them for a little cheaper I think, but go with the 185's if you plan on stroking it

But answer these questions, this is all I need to know about the AFR 185's:
1. Can I use them now with stock pistons?
2. Will I notice ANY gain?
3. Will it be fine for a daily driver until I have enough for the stroker?


That's all I really want to know
if not then I'll just save my money and get it all at once
or just find some used Edel Performer RPMS cheap on ebay and run them til i have the cash for new afr 185's and the stroker 347 or 331

1. Yes
2. You will notice a gain, but at a higher RPM because they are high flow heads
3. They would be a little at the high side but you could make them make due as long as u dont have a radical cam.

1) According to the tech information on the AFR 185 heads in the Holcomb Motorsports Catalog, the 2.02" intake valves in the 185 heads require bigger than stock valve relief notches in the pistons, so if you still have the stock pistons, you CANNOT USE the AFR 185 heads, you have to go with the AFR 165 heads which have the 1.90" intake valves.
2) Yes you will see a gain with almost any new head with bigger than stock valves
3) YOU NEED NEW PISTONS WITH LARGER VALVE RELIEFS IN ORDER TO RUN AN INTAKE VALVE LARGER THAN 1.90", SO DON'T GET THE AFR 185's.

You could notch your pistons you have now I believe.

Just save your money and wait man. You are better off doing it all at once. Take it from someone who knows and has done it before.
