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.

When building an engine from the ground up, calculating the compression ratio (CR) is a necessary step to ensure maximum performance and prevent future problems.
