sbc #434 heads any good?
are there any flow rates or specs available for the the SBC #354434? Mortec says it't a 75-79...262/267/305...60cc chamber.
Any body got any more info? Thanks |

Good heads on a 283/305/307, but a little small on the valves/runners on the larger sb mills.....:crazy: L

Are these the 74-76 262 monza heads-- I ran them on a 283 -- I believe it lowered compression on my 283 to around 9-1. They have the hardened valve seats for unleaded.

They should be the same comp ratio on a 283, as the old "520" casting was (60cc power pac head). the old 4 brl 283's didnt run too bad;) :crazy: L

I was thinking about using them on a mild 350 but sounds like I should keep looking...
