LS7 failure
Any links?
Im glad i went with Mast Ls7 heads on my 427ci build. My builder knew Cary for years, he was with Cartek(Mike) way back when. He swore by them. Gave me alil history on Horus Mast n Cary... I was reluctant,$$$... but Yolo, all in!

I've always wanted to try the RHS LS7 heads and have heard a lot of positive things about them. Brodix, AFR/MMS, TFS, etc all make decent heads, it just depends on your end goals.

KCS who told you this......Several Top porters and avg guys have had problems with RHS head castings. They lost the original guys who did the castings. Ask Chris Frank or Dennis Wheat, Dennis broke it down when the heads went to trash. Maybe they've got someone new ....if not pass. They were cracking all over the place without any FI application's used. Know of 4 on YB. Even made a RHS head thread on YB.

Yeah that was when they 1st hit the market. Then RHS was sold to Comp and all went the crapper. Casting foundry switched and then the problems began. Chris couldn't get a set after the switch and casting flaws were seen. Purps 440 heads cracked in the exhaust if I'm not mistaking, another one cracked near the head bolts. Talked to Dennis when I did that post on YB, contacted him thru FB and he told me to call him and this is where I got the tea...or information. Chris knows as well. But Chris F series heads have features of the RHS. Longer valves = higher runner placement generally, valves run 5.8 to 5.9 length damn near All Pro c5r heads length @ 5.9 to 6 inches.

Eric said his winning 370 was a slightly bored 5.3 with a stroker, *✓°> heads flowed 415cfm on a 3.900 test bore with a Holley Hi ram intake. Liberty 11 degree Ls3 heads. 740ish with 12.1 compression and max cam lift of .775
Yeah you read it correctly 415 cfm with a 3.900 bore tested.
