How many k's have the heads done, and what condition are they in?
What did they flow before and after the porting?
I'm thinking about whacking these on my car but not sure if they will be a straight on... u are running a 347, and im only a 302, should it still bolt up?

They are for 5 Ltr as said above for forced induction 9.5 comp is too high with these heads..They have done 20.000 klmrs..Will require hardened pushrods..You can negotiate the roller rockers..Ported by Benny Gatt...No numbers but flo 280cfm easy..These heads made 269 rwkw on 7 Lp @ 4800...Springs duel being track heat will take up to .600 lift.2.02 inlet valves will fit on std piston with std cam with 1:72 rockers..Most other heads with this size inlet the pistons need notching...These are good heads.I may still use on same 5 Ltr block and put in something else...

331 with 4.125 bore = 350ci..

bugger no go. I'm running 9.5:1 comp pistons, otherwise they would be ok, i'm running a 2030 crane so that'd be ok and the pistons are already ok for that on the ported heads that i have.

Doh! i even had my eye on some 1.6 rr as well....
