Default Need opinions on these heads and flow #s..

there are used 98 heads I am considering to buy

they have 2.020 intake and 1.55 exhaust flow
.300...137..108
.400...202..135
.450...232..166
.500...254..184
.550...270..197
.650...273..203

would 15rwhp be possible with these #s?
thanks in advance for any advice.

Are you getting a good deal on them. They flow alittle better than stock but not much better.

Don't waste your money for 15 hp. The gaskets would cost more than the change would be worth.

Flow #'s can be very misleading.Those #'s are comparable to LS6 unported heads.To compare you need the port volume(cc) and how much they are milled to get an idea.I would think a 15hp gain on a stock Cam is about right and around 20-30hp on a aftermarket Cam.

Don is right about evaluation procedure, but unless your lift points are mismatched with flow numbers than these heads are way down on flow at 28". You need to double check this, because you dont want heads that actually flow this little.
