I'm thinking about upgrading my heads. Which heads would give the best results when using the MTI B1 221/221 .559/.559 114. I don't plan on using nitrous or FI. Should I go with a Stage II 5.7, or 5.3 for more compression, or even the Patriot LQ9/LS6? I know the LQ9/LS6 whould be over kill for this baby cam (by todays standards), but if I ever do go with a larger cam I won't have to worry about heads. Are there any drawbacks to using the LQ9/LS6 with this little cam?

I'm loving my LS6 style heads. I think they would work great with a "smaller" cam. I wish someone would go ahead and do that, I'd like to see the numbers they get.

since you plan on upgrading your cam in the future, or sound like it, i would go with the patriot lq9/ls6 heads on a 59cc chamber

I say 5.7's they work. Period.

bryan, let me know what you decide. as a fellow B1 owner, i'm interested in your results. as a recommendation, i would look for a head that flows 300 cfm at .550. i would think that can get us to 420-430 hp.

Back when I was running the lil TR220 and Patriot stage II 5.3's I was making 416rwhp and 392rwtq on stock programming. I'm sure a good head with the B1 will get you that with all the bolt ons.

I bet the new MTI Satge IIE would work well with that cam.

I like to get a set of heads, have them flowed and match the cam to the heads, not the heads to the cam.

My MTI Stage II 5.7 heads milled to 60cc chambers produced the results in my signature.

Go with Stage 2 5.3 heads. Get the extra compression bump for free! If you're not going F/I, then take what you can out of the heads.

Thanks for all the replys. I've actually emailed MTI about the STG IIE, but they haven't replied yet. It's only been 2 weeks, I'm sure they are busy getting ready for the shootout or something.

I have the T1 cam which is practically the same as the B1. I am going in to MTI Monday for a Stg IIE head install. We will see what it will do then.

IMHO- paying the extra for an LS6 style head may not be worth it for an N/A 346 application. LS6 style heads shine in FI & bigger cube apps.

I talked with MTI about the S2E's which I think are a sweet deal today. They seemed pretty busy, I was told if I ordered today it would take 2-3 weeks for them to do the heads.

When I asked after overlaying the S2E flow graph with the S2R flow graph and seeing they were almost completely identical...if I recall correctly...MTI said...

You are not missing anything. We have developed a way to produce a 300+ CFM head w/o bronze guides and larger seats for $1595. exch. These heads will flow the #'s advertised and we will give you a flow sheet for your exact set of cylinder heads. These heads have been proven to work extremely well but I do recommend you install headers instead of keeping the iron manifolds in place.

The MTI's and the new TEA 2.5's are high on my list...along with LG & Absolute.

I agree, but will they hurt performance compared to a 5.7 Stg IIor 5.3 Stg II?

TVWilkes

The LS6 style head will not hurt performance vs a 5.3.On a stock bottom end you will have a gain from the LS6 style vs a 5.3,but it will be relatively small,around 10 rwhp.The head will shine if you go bigger cube later.
