Is the B1 the right cam for MTI Stage 2-R Milled heads? What the title said: Is the B1 the right cam for MTI Stage 2-R Milled heads?
I did HUNDREDS of searches here and didn't find anything on this combo. The milled heads will give 11:1 compression.
B1 cam or something else? What do YOU, -- Tech Addict -- suggest?

The B1 is the baby of baby cams. It is the one that started it all.

The B1 will fit, but it's gonna be CLOSE. I would check PV clearance, and recheck it again.
If your heads are definately milled that much, then you'll have a hard time running anything bigger than a B1 if it'll even fit.

Man it might be close to 400. But that cam is so small. I would not get heads that milled. I would go with a set of heads that have stock deck hight and do a nasty huge cam.

Yeah that's what I was thinking... but it would be a good setup for a daily driver that carries the wife as passenger once in a while and all... don't you think?...

You will have to scrofice a lot of deration for the milling. You can make more power if you have stock hight heads and a bigger cam. Man i wish you could hear my 228 cam on a 114. Has a little lope but not much. With a good ported head you can make 400rwhp or be realy close. IF you have a stick you sould be over.
I made 390rwhp unlocked with that cam and a set of ported ls6 heads.

Isn't it true that the B1 is a 221 but it actually measures 224 (on 114 LSA)?
This whole thing is confusing me 'cause I don't want to waste my money... I want a daily driver with aprox 435rwhp. My car is a 6 speed. (mods listed on post #5 above).

Stage 2R Cylinder Heads
Intake and exhaust ports are fully maximized for flow volume, and port velocity. New hardened intake and exhaust seats are installed along with bronze valve guides, and custom 8mm one piece stainless steel Ferrea valves measuring 2.055" on the intake, and 1.60" on the exhaust. High performance dual valvesprings coupled with our custom lightweight titanium retainers and specially machined spring cups offer the most stable, and reliable valvetrain. These heads can be milled .030" to increase the compression ratio by 1/2 of a point. These cylinder heads power some of the quickest and fastest LS1s & LS6s in the country. This is an excellent cylinder head choice for those considering a larger displacement engine in the near future
This is what MTI said about the S2R heads. They can be mill .03 not .055
If you dont have the heads milled you can run the G1 or the R1 cam witch should net you the power u want. As long as u ditch those cats u have there.

The B1 is a great cam, older technology but a great cam none the less. Through a stock 10 bolt and good heads, you should see 415-430 depending.....

Like goober said .055 mill is a lot.
1- it affects your flow output (reduces it)
2- You might also have intake seating problems.
.030 mill should be enough with a thin gasket and a tight quench (~.035 IMO) like a .040 (AFR cometic), .041 (felpro) or .042 (Mr. Gasket)
Would prefer the MTI 2E 5.3/ X1 combo myself.
