Not apples to apples, but just for info. We used a squash of .020, no gasket, O ring, & turned 13 to 14 rpm with our 2 stroke 250cc motors. Cannot remember the cc’s for the heads. But it took many, many hours with 400 wet paper, WD40 & a surface plate to achieve
the desired combo.<br>

Amici,

</div>
<div>Building a small journal 1296cc Spitfire.</div>
<div>Running Venolia’s over Carrillos</div>
<div>been know to go to 8500K rpm (occasionally).</div>
<div><br>
</div>
<div>Going to have the block/pistons decked to zero. (can someone tell me a better way to say this?)</div>
<div>Anyway, I realized that my quench clearance would be the crush thickness of the head gasket.</div>
<div>.035 ~.0385</div>
<div>In the Comp Prep manual it states .025 as plenty of gap. </div>
<div><br>

<div>Just want to see what y’all say.</div>
<div>Thanks, </div>
