65 CC Rpm heads they are new and I just dropped them off at Killians Porting Service in Warner Robbins GA have heads ported and tunnel ram port matched and competition valve job done . Im building a 340 for my 51 Henry J gasser to be raced not street legal so I need compression.
Yes the 4.080 is my problem and I also would like to get lite items if possible I will go on Mahle website and see if they have something thanks again.
65 cc on heads looking for 11.1 or 11.5
I checked all the major piston manufactures wedsite and plenty of 4.00 stroke 340 stuff but not so with stock 3.31 stroke.
