Porting tfs 205s

They are also a lot cheaper than the TFS215... like $450 cheaper. Enough to offset the cost of the roller rockers or pay for installation of PM guides. And for just a couple hundred more than the TFS 220s; they have similar flow but better port velocity... all while having a much smaller chamber.
I almost wish I knew more about them last year when I bought my heads. I would have given them a try with a big cam. I wouldn't have had to flycut.

them bare...pop in some hollow LS6 intake valves and have near 12:1 comp
with a thin gasket and PTV clearance for a T-Rex sized stick..***** Thumper
Look at all the fun you had with your friend Lindy Tool.....
But the TFS heads offer 58cc at better than stock PtV Gary... when you mill, you kill your clearance, even with the TFS heads. Especially to get them down to 58cc.
And yes, running the hollow-stem LS6 valves would be awesome!

I don't know. Gotta measure lol.
A 231 intake lobe on a 108 ICL would still clear I would think, but be tight. I'd feel better with a 231 on a 110 ICL (with LSL lobes). Going to a 235 or so on a 110 would be tight.
