Questions regarding IMM Indy MAX heads.

Dragonbat13 said
I am wanting to get a set of the Indy MAX, Magnum type heads with hydraulic roller beehive springs from Brian at IMM. The special he advertises. I want them because they seem to be a good deal and they can support upgrades in the future.

But with all the other stuff going on I really cant afford a top end along with a stroker build (future upgrade, but way down the road). So what I plan is a basic rebuild on a magnum 360, if necessary and install the heads along with a magnum specific performer RPM intake, holley vac secondary carb, TTI Step headers, custom grind cam and custom torque convertor. The rest of the car is listed in my sig.

I am somewhat concerned about the heads being too big for the 3.23 gears.

Will the heads be too big and kill low end?

Also, can the MAX heads be drilled to accept both styles of intakes?

Hello there, I will start by saying I have no experience personally using those heads.

If I read your post and understood correctly, you are looking to build a performance engine in stages due to budget constraints. I completely understand the budget thing and the struggle to find money for like to have projects.

If I may make a suggestion, build a really good shortblock first, then get the better heads down the road. While factory heads certainly will limit the potential of the engine initially, a head swap down the road as budget allows will be a piece of cake.

I have found other members on this site to be excellent resources for great parts at fantastic prices.

Just my opinion, best of luck with your project.
