I do not sell a different casting than what my auctions states. I will save you the time. We use 416 and 450 SBC castings. Yes, the are early 80s 305 castings. Now just listen to the next part. They start out as 305 castings with 58 cc chambers. the port runner volume is about 150cc in volume as a 305 casting. With all the machine work and other modifications, the chamber size goes up to 64cc in volume. The intake port runner volume goes up to 160 to 165 cc runner volume. This is due to the bowl hogging to put the bigger valves in them. If I have not given you the flow figures on the heads, go to this URL
http://amperformanceheads.com/64ccflow.htm
If you have done your homework on flow #s, you will see that these flow very close to what the old camel hump or double hump castings flowed (461 or 462 or 186 or 492 or 041 castings) and these casting were the performance castings that every one wants. That is untill the newer Vortec castings came around.
Now this is also reflective in the price that I sell them for.
So all I am saying is really check out the machine work before you go off and say 305 heads are junk. They are junk as a 305 heads, but modified as we have done, they flow better than some 350 heads.
