I need at least on 3A head. I have a broke valve cover hole and I am leaking oil. Had a set found a year ago and passed them up. Any help? let me know a price with shipping to 72761.

 

I'd rather sell ya a set of #3's so you can pick up some compression if you're gonna go that far for just a broken valve cover bolt....

 

3's have the 7/16 head bolt right? I have 1/2 head bolts on this motor. I have heard you can have them bored but scared to get the walls too thin. i have a set of #5's, 7'S and #8's if that is the case.

 

It just takes a drill press and a 17/32 drill bit.

 

Thanks for the info on the drill bit. I may use the #7 I have.

 

I've got a #3 and a #6 bothe fresh not sure what's been done to them as they are on a 73 350 with new pistons fresh crank 10/10 I'm not sure how someone could run two diff heads but the guy I bought it from said the motor was running in a delta they pulled it and sent to machine shop ...... What I can see is screw in studs and guides with 1.6 roller tip rockers
