Stock LS7 heads on a LS3 416
I got a good deal on some LS7 heads with bronze guides for my LS3 416, I was wondering if I change out the exhaust valves to a 1.59" would this clear my pistons. Any info would help.

I think you can Call RED racing engine's in Colorado they did a engine with small bore and LS7 heads for engine masters challenge EXH valve was I think 1.560 I have the mag I'll go check.

Does this seem like a bad idea to anyone else but me? The LS7 heads are good, the intakes flow exceptionally well, the exhaust, not as well. That's why most LS7 cams have a large split, favoring the exhaust. Now you are going to put in a SMALLER exhaust valve, and shrouding it against the bore?

To MDTJ: The last to threads hit the nail on the head. RED also shrunk the port to 256 cc stock ls7 port is what 270cc or 264cc without cnc machining.Check out LS3 heads Mast or buy TFS ls3 as I did for my 408 even though I bought mine bare.
