turbo heads

hey guys im looking for a good set of turbo heads the bottom end is forged 5.3 bored 20 over so its 3.8 bore size.... Im trying to find a set of heads with a 72cc chamber to lower the compression but has valves that are not too big for the bore size so i dont run into any valve shrouding issues from the bore size being small...

I found these heads the deck thickness is great but just not sure about the valve sizing

Well the 317 heads use 2.00 inch intake valves and 1.55 inch Exhaust Valves and there are guys making damn near 1,000RWHP with those so I would think those World head valve size are just fine.
