I have tfs cast heads that were used on my 347. Now have a ls2 shortblock on the way.
Would like to team the 2 up, but am nervous about compression with pump gas.

Using compression calculators and 0 deck static compression is around 11.75:1 with stock gaskets. I have a f11 cam 228/230 114 lsa, but understand I will probably have to go larger to make the dcr safe.

Considering flycutting, swapping pistons or having a little taken out of the combustion chambers, but money is pretty tight at the moment.

Please chime in if you are running a similiar or have experience with a similiar combo. Thanks-Garrett

Gonna get an estimate on enlarging the combustion chambers tomorrow. Thinking this may be the way to go, I could then run thinner gaskets for better quench and be able to reuse my f11 cam.....

I calculate your SCR to be 11.71. I wouldn't worry one bit about DCR, it's just another number that doesn't mean a whole lot.

IMHO, you will be okay with 93 octane as long as your tune is spot on.

I was running 12.2:1 on my stroker with 91 octane most of the time and 93 when I could find it. Never had any problems once the tune was smoothed out.
