is 10.34-1 too much compression for todays gas?

[moparnut]

I have the opportunity to get a slightly used set of trw L2295 pistons at a good deal.With 88cc heads compression would be 10.34-1 is that too much and how much can i take off with different head gaskets and which ones?thanks in advance Chryco,lol

My Hemi is 101/2 to one.  They are a little more tolerent of compression than wedges, but I run pump gas all day long with no problems  Oldschool

yes & no
 the domes can be trimmed off to lower compression , or you can use a thicker head gasket to decompress a little
 it really depends on the cam , a short duration cam will build a lot of cylinder pressure & puts the powerband low where it will ping , a long duration cam will do the opposite & should be Ok & generally will not ping in the 2500 rpm range where the engine will make power , you will also need a loose converter with 2800 stall so no load is on the engine where it would ping
 I don`t like the 2295 piston for flame travel though
