Hey Guys, I've got a set of Speedmaster heads on my 360 1972' block.. obviously non roller block, everything pretty well bolted up without issues even alternator... I did have comp cam springs installed/and the retainers to but I used the Speedmaster valves.. I noticed the valves are lil bit lighter than what I'm used to feeling but heads are fine according to Fast Teck Machine shop in Ocala.. i only have about 100 miles now but doing great! I did use Speedmaster head stud kit with only 70lbs of Torque according to Speedmaster Torque spec is just 65lbs.. so anyway they seem great in my truck..its not a race truck it's street drivin and feelin like I'll probably order another set of Speedmasters for a 71' 340 I'm doin... so far I'm happy... Nice heads!

I got my cnc heads bolted up to my 340 earlier this year and have a couple hundred miles on my car. Bolted them up right out of the box and they have been great. I’m not sure if I have anymore power than I did before though? I know as much about tuning as a fat kid knows about dieting… lol

I’ll be getting another set for my spare 340 block as well. Going to get some of their rockers too!
