I have the 195cc street head 68cc straight plugs on my 10.3:1 383. Just arrived 2 weeks ago.
Here is your only problem with AFR. If you dont find someone with these heads in stock, you will need to wait approximately 10-12 weeks. Why? AFR doesn't build you head until you order it. Next issue, 210cc race head only comes in 76cc combustion chamber (this will lower your compression ratio---call your piston mfg to determine what cc head you should order). It will cost more to have them milled. The 210 comes stock with roller valve springs and you will need to indicate if you want that downgraded or you will flatten a flat tappet cam in no time.
The 210 only comes in an angle plug configuration, straight plug is a special order (non-returnable).
195 head may not clear domed pistons.
195 comes in 68 or 74cc configuration.
Also, use ARP head bolts.
If you must have AFR, call around for stock. Also, call AFR direct for advice. They will assist and give you their recommendation.
Also, make sure the roller rockers you have/are buying will clear the large valve springs that these heads come with.
