So I dug these out off the shelf to possibly put on the 350 in my wagon since my 406 has taken a different turn and I’ve had thoughts of having these freshened I believe these to be phase 2 bow tie angle plug heads when I got them 15+ years ago I was told they were ported by Brzeneski which is very possible since his shop is less than an hour from my location. Existing 350 good 4 bolt line honed and decked flat top engine with world products Sr torquers and mild .480 hydraulic flat tappet. I have a comp.510/.520 hydro roller with 1.6 rockers that I’d like to install in 350 but SR heads would need guide plates(machined) and pushrod holes and valve guides cut down to make work and only are 170cc
Option 2 is pressure test clean and check bow ties probably New valves and valve job. Both heads will need new springs so that’s a wash. I have 1.6 pro magnums for 3/8 stud and crane golds for 7/16 studs so that’s covered. I know there are way better heads out there but 1500+ isn’t in the budget and I have a older set of Brodix in the basement for the 406 build. Car is a 57 210 wagon/3700lbs ran a 14.26 97mph with ****ty tuned carb. Since then went from stocker 3.55 rear to 4.10 quick performance 9” and has 700r4 with BM 2400or 2600 stall. Intake is a RPM air gap but I have other options if need be. Any thoughts or opinions are welcome. Just trying to get on road this year to enjoy, Sat all year last year cause of health/recovery issues. Cars plan is double duty street/track car.
Thanks in advance.
