AFR's website lists the 210 as a standard valve placement, standard girdle head. Their 215 RR requires shaft rockers, the 227's use offset girdles similar to my Brodix 11X heads. If your old 195's are different/offset, you will need new girdles. Try them first. Heads with offsets are significantly different, you will know immediately.

I've owned 210's 220's and 227's
The only thing I used special on any of them was the stud girdle on the 227's, some people even say they need offset lifters but I never ran into that trouble with them. 210's needed nothing special.

i dont have the heads yet i ordered them last week they say up to 5 weeks.the reason for all of this is that my 195 heads now have 3/8 rockers on them rather than buying 7/16 rockers for the new 210 i would swap out the 3/8 studs and my rockers and the stud girdle and sell my 195s with 7/16 studs.i dont want to fork out 300 more bucks into these heads for new rollers already expensive heads if i dont have to.would 3/8 studs and girdle be just as strong as 7/16 studs??

I have the 227's with the 60/40 valve spacing. Had to have the stud girdle for them, was able to run the standard rocker arms. However did have to use adjustable guide plates to get proper roller contact on the exhaust valve, primarily #1 & 8.... Coincidently these are the same valves on both heads when sitting on the bench?????? :wink:
