Got my hands on some TF 270's (flow results)

I’ve had a dozen or so sets of TF Mopar heads in the shop.
My only complaint with any of those sets were....... the guide clearance for the first few couple of years was very tight.
I had some where the clearance was as little as .0004”.

It would appear a conscious decision was made at TF to open that up a bit.
The last few sets I’ve had here had the guide clearance at .0010”-.0012”.

My other complaint is, for most flat tappet applications, I feel like the “middle” spring package is too stiff...... especially in light of how many people are experiencing cam & lifter woes.
