Thread: Heads?

Tweet

hey everybody, im building a 355 for my 72 monte carlo, and i had some questions. im trying to decide what heads to get. ive pretty much decided on aluminum heads and i was wondering what people have heard about certain ones. ive heard some good things from pro engine builder about the Jegs 197 heads, but after googling ive found some people saying that the machine work isnt very good out of the box. ive also been looking at the dart pro1's. any feedback on these or any other great heads in the same price range would be great. if you can find better for less money thats even better
im not sure exactly what parts i have already, im going to my grandpas machine shop tomorrow to take apart the rest of my bottom end and see what i have to work with, as well as see all the parts he already has for me. im pretty sure he has some nice flat top pistons for me, and i think he has a racing cam from my cousins dirt track car. ( he raced it for one race and totalled the car...but the engine was a-ok ) thanks for your time and help

i think you would be safe with any reputible manufacturer, dart, edelbrock, world products, and if you have the bigger bank account, go for brodix or AFR. im not sure who does jegs heads but i know they will stand behind anything they sell if there is a problem. as for the circle track cam in a street car application. its a whole different kind of power in that grind. usually made for alot of constant high rpm top end power, not to street worthy. and if you got power brakes probably not the best cam choice.

These would be my choice for a 355 Chevy. In all the dyno tests I have seen with these heads, they are far and away the best choice for an aluminum head.

just to clear a little bit of info up, the jegs heads are manufactured by canfield. im not sure if canfield does the machine work on them or not, but from what ive seen on the net, they are definately canfields. which also seem to be decent heads. ive heard good things about canfields.

We need to know how many rpm's you are going to turn the engine to pick a head for you.
