It depends on several things, which type of head, iron or aluminum,probally the type of fuel, alcholol ,E85 or gasoline, is it a closed chamber or open chamber head and do you mind increasing the CC of the chambers? I've seen stock cast Iron 426 Street Hemi head vary 4 CC between chambers Same thing on a set of stock 906 iron heads

I was always told it helps reduce detonation. I did my Hemi heads that are aluminum. Polished up real nice...Don't know how true it is, but its cheaper than the Swain Tech coatings I was looking into.
