I recently put a set of m400 heads in the shop to get them machined to fit my 69 302. I chose to go with the stock 2.04 valves intake and 1.66 exhaust one to not lose to much bottom end and the fact that around here its hard to find these type of heads so the 2 barrel version was a little easier to find especially since i'm using it on the street. I am having trouble finding where to buy the right pistons to go with the heads. I have looked in several places but i have only found the Ross Racing Forged Pistons and they are like $560-$756 for a set so any other place they can be found please let me know thanks.
