These heads a a great HP adder for that 306 Allen. I would recommend a TFS stage 1 cam and Street Burner intake, These will handle a 70MM throttle body and a free flowing exhaust.

I have a 1989 convertible Mustang that I am currently building a 331 stroker engine for. The stroker kit is using flat top pistons. I want to run AFR heads. Are these a good choice, or should I use a 165? I am using a GT40 upper and lower intake. I do not have a cam, are there any reccomendations?

Honestly that intake would choke down that motor considerably. They barely kept up to 302 cubic inches. Depending on what kind of HP you are looking for, the TFS top end kit is a easy 375 HP on a 331 with good compression.

Hi I am going to build a 347 stroker motor with a Holley systemax intake an the AFR 185cc intake and 58cc combustion, I will also be using a comp extreme energy cam and the stroker kit is going to be all forged parts and I will probably use dished pistons will all of these parts go good together and at the same time still be drivable on the street, also will this give me good hp. I will also be running a vortech v-3 supercharger with about 9lb of boost. Thank you

Hi I'm going to build a 347 stroker motor with all forged parts wanting to run a rpm 2 intake and the AFR 185cc in and 85cc combustion, I will also be using a turbo camshaft and the piston ratio is 8:1 on the kit will all these parts go good together and also would my car be driveable ont the streets. Would this setup give me good HP? I will also be running a 76mm Twin Turbo with 10lb of boost. Thanks

These heads will go perfect with a power-adder. Depending on your cam spec and the stroker assembly we would recommend to check for PTV interference when installing them. Without knowing your current head combo I couldn't give you a honest answer in regards to 'will it give you good HP", but overall these are a stellar performing head out of the box!

Hi, I am building a 347 stroker motor and I'm using a comp can extreme energy cam 232/240@.50" to be exact and I want to get the most HP out of the motor what AFR heads should I use and also I am planing on using the Holley systemax intake with a 75mm throttle body. Is that a good choice? Thanks

These heads will flow substantially more air that the ported intake manifold will efficiently flow. It will function but you will be choking down your performance possibilities. It would be highly recommended to get a better flowing aftermarket intake for your set up.

It will depend on what other components you will be running with these heads. They should work with no problem but if you are running a large cam or higher ratio roller rockers you might have issues. You always want to check your piston to valve clearance before you start your motor any time you do any head or valvetrain work.
