does anyone here have a set of canfield heads on their car? i am loking for some help, did you have to flycut the piston for these heads? i am looking to toss some on a 351w and i am loking for 10:1 c/r and i am not sure if i have to flycut the piston or not.

thanks all.

rhs all the way, in comparison to the other 2 choices

what about compared to canfield??

mattdel

rhs & canfield are pretty much side by side in flow numbers, if i recall. still above afr and TF, either way.

Here are flow numbers for all heads.

Do you need to get dished pistons or larger reliefs for the pistons with canfield heads on a 302 or a 351w?

^^ that was one of my first questions, i am wondering the same.

and why must i have a larger chamber with a blower application?

would a 215RHS heads with 64 cc chambers and 2.08/1.6 valves be ok for my blower a couple years from now and good performance now with my N/A setup??

thansk all.

you want lower compression ratio for boosted applications, unless you are ready to run some pretty high octane fuel...
the larger the chamber, the lower the compression ratio. then you add in your pistons, and figure out what its going to be.
any piston you buy should have documentation about the ratio it provides with a certain chamber.
