How much hp is needed until you would recommend upgrading to the stainless steel valves, titanium retainers, and high performance springs?

 

[Modular Racing]

We suggest them for over 300HP na and over 500 Supercharged. Please let us know how we can help!

There is no gasket for the rear seal plate, they use silicone from the factory.

Do you have any flow numbers against fox lakes heads? I currently have Fox lake stage 2 heads and make 597rwhp

 

[Modular Racing]

Each MMR stage outflows the comparable FL stage by 5 cfm on both the intake and exhaust, this of course was done purposely to set our heads apart from theirs. The FL heads are nice heads, these simply flow more when comparing the same stage.

So if i purchased your stage 3 heads how close to 650 would they bring me?

 

[Modular Racing]

Tell me more about the combination and we can give you a HP estimate.

Vortech S trim 16psi , FL stg2 heads, comp 270cams, trickflow intake, longtubes makes 597 right now.

 

[Modular Racing]

You should make roughly 20 more rwhp over your existing combination.
