Motor build

Hey guys I just got my 454 out of the machine shop and got it bored .60 over I got the eagle steel crank and forged pistons. But I need help finding out what kinda heads I should get any suggestions?

Without knowing a lot more details can not give you specifics. Recommend the Summit Racing site and make a selection there by using the filters they provide based upon other component choices, camshaft, compression ratio desired, intake choice, and type of usage the car will see, street, street/strip, strip only.

Ok I will thank you I know it’s 10:1 compression and 4.25 stroke 4340 eagle crank with H-beam 6.385 rods so I need to find intake choice and cam before I choose the heads?

You should buy a complete matched top end package and how can you know the compression without knowing the CC size of the heads?

Hey sorry I’ve never built a motor before still learning things but I meant I’m wanting it to be at 10:1 compression

You need to know a number of measurements to calculate the compression ratio. The machine shop that did the work can supply you with those numbers or you will have to do it yourself.
