Out with the 340 & in with the 410 stroker!
Flowed the driver side head 3,5,7 int ports
here are the numbers
.........3.......5.......7
.100 64.4...65....... 67
.200 132....134.7....135.7
.300 195....194.8....195
.400 240....242.......245
.500 270....272.......276.8
.510 272....275*......277*
.550 278*...270.......262
Probably gonna leave'em alone, I want to keep the low lift up and I'm pretty sure at this point if I keep going to get higher peaks..it'll be at the cost of the low lift flow or possibly water depending on the amount of core shift these heads may have, I can go wild on another set later..
I kinda think if I want a lil more...I can go with 2.05 intake valve and a better valve job with a 'porters designed' cutter, since with the bigger valve it will not sink the seat more than it is.
fwiw
