Power adder car or nat. aspirated? Auto or Manual? What gears? Have you mocked up the valvetrain to see what you have for piston to valve clearance? Those Sr's have 2.02/1.60 valves and flow very well to almost .600 so a TFS1 would not give you your full potential of your heads. It is usually recommended because of its price and thats all anyone really knows, there are many OTS cams that will benefit you much more than a TFS1. Just my 2cents take it for what u think its worth.
with TRW 2482's flat top and a 1.94/1.60 valve combo I have run .550 lift cams and had .090 clearance with a .032 head gasket. You could use your old cam to check with if you don't have checking springs and indicators. Use they clay method with your old gaskets(they are already compressed) and rotate very slow if you feel a bind abort mission! That old Lunati is not actually a bad little roller if its not bunged up. That should put you right at 9.5 with those flats and the 58cc chambers so you could use a little bit of camshaft.
Depending on whether or not you have the 2482 or the 2488 piston with the 82 you will have 8.7 and the 88 you will have 9.5. In either case I see a blower or NOS in your future. Those heads are heavy decked and tough as nails I would not be afraid to throw 150 shot or 10 psi(properly tuned) at it. Get Felpro 1011-2 h. gaskets that way its done right the first time. It will not kill your power it will be a bit soft down low but your 4.10 will absorb some of it. I would run a power adder style camshaft and look for a p/a in the future to spice things up a bit!!!
