Had the new heads flowed

Looks like the new pro topline 220 heads are pretty good right out of the box

numbers>
all are tested @28"
.200 131 I 91E
.300 186 I 125 E
.400 235 I 148 E
.500 267 I 163 E
.600 288 I 174 E

I stopped at .600 because that what the cam is .625 to be exact.
My buddy said that just putting in a 2.05 valve in these with a bowl clean up will bring them to over 300 cfm intake. The exhaust was done without a pipe and would be higher.

All in all very happy, Now on with the 406 to see how these work.
