Looking at buying a set of afr 215s off somebody. Problem is I'm not sure if the chambers will work without flycutting. They have 60cc chambers and planning on running a 226/234 598/605 113 or the torquer v3 with a 111 lsa. Running a stock bottom end ls6.

That may be cutting it close. The only real way to know for sure is to measure. I'd take the 215's for sure over teh cam if it were one or the other. Those are great heads and anyone can spec you a cam that will work with them. The low intake duration on the cam may be your saving grace. You want around .080" clearance on the intake and .100" on the exhaust ideally. The heads also use a lower valve angle which helps with PTV I think. 13.5 vs stock 15*

It all depends on the price of the heads I suppose.

Stock valve angle... and less than stock PtV clearance... Tony usually specs a 227/231 114+1 for them to fit without flycutting... but with 60cc chambers, that might be close.

Thanks for the heads up. But a 226 intake duration he has may squeak by. Still should check. Without a doubt.

****, Dr. Whigam on here ran a 230/236 on a 112 LSA with 59cc AFR 205's and he didn't have to flycut. I'm not even sure he measured, but he ran the car like that for a long time. He's a M6 too. Best bet is to measure.

Just hate to buy them and not be able to use them

I would 100% buy the heads and if the cam didn't work swap out the cam. Those are really good heads.

Agree, or just flycut. You can rent the tool.

Not fly cutting. And that's the cam I want to use, or a bigger cam spec'd by tick. Either way I may just buy some tfs ascasts or tfs 205s

Which cam? The Torquer V3 with LSK lobes that will eat your valvetrain alive in 8k miles? You need to make sure you setup your valvetrain for that lobe if you plan to drive the car often.

Btw, flycutting isn't that bad.

Probly won't go with the torquer v3. Probly get a cam spec'd for the heads. But I'm still not going to fly cut.

Flycutting is fun!

Still not doing it.

I still think that cam will clear those heads. I'm pretty damn sure someone on here runs this cam with AFR heads milled more than yours. Read my first post about Dr. Whigham.

Measure.....

Think ima just wait, get a set of tfs 205s later on and have a cam spec'd for them.

Why TFS 205cc's and not TFS 215cc's or TFS 220cc's?

I thought the 205s were for the 5.3L?

Tfs 205s have 2.000 intake valves. Tfs 215s have 2.040 and ascasts have 2.055. I gain more ptv clearance with tfs 205s and can make more tq with smaller chambers.

They are for a 5.3 but they'll work on a 5.7 also. My brother has a set on his c5z with a 234/242 6xx/6xx 110 and it makes great tq considering the size of the cam.
