Cylinder head selection Empty Cylinder head selection

Post  EverySparePenny July 8th 2020, 2:03 pm

Working towards a 480" ish truck pull engine, iron block aluminum headed, ruled to nothing "bigger" than an A head. Goals in mind are 2+ horse/cube heavy on the + side, peak hp somewhere in the 8000's for rpm and 9000 or just shy of operating rpm.

Do I go straight to the A head? Is the SR 71 "enough"? Is there some other head I should be looking at?

Thanks

I am debating the same thing, but with more cubes. We do not have any cubic inch limit. I am planning on running a 598 or a 612 and most likely will go straight to the A-460 heads.

Personally, everything will be determined by how much money you are willing to spend on this project.

You are looking at an early 90's Pro Stock type engine but, a smaller bore ... 4.530", (instead of 4.625") x 3.700".

Wave tuning is the game, can you get the intake and exhaust in tune to make power in that range?

Eliminator is working on putting out a A+ head that has revised valve angles and a rotated combustion chamber.

A tunnel ram with "A" heads would be my personal choice here.

Go with the TFS A-460 heads,,, but not a set off the shelf. Your professional Ford custom engine builder will probably want a bare set, or even an unmachined set to install CuBe seats, have a smaller combustion chamber, a full set of titanium valves, and shaft mounted rocker arms such as W.
