Fantastic Jacob!!! Yup those are the heads I want to be running!! 🤣😝🤣😝

[@GrandPitoVic]

Those heads are gorgeous brother. You guys really did a great job with those.

[@chrisobrien9334]

There beautiful. Lot of thought has gone into the componentry used in these heads. Great work mate. Support from 🇦🇺🇦🇺🇦🇺

[@jonathanmoore5112]

DUDE I think those are my heads that I just ordered last night. Moore Racing and Performance

[@JacobVillemain]

Yessir!

[@jonathanmoore5112]

@@JacobVillemain Awesome! I’m looking forward to seeing what they can do

[@paisley2342]

​@@jonathanmoore5112 what was the setup? Gains from these? Looking into them currently for my LS3!

[@jonathanmoore5112]

I was running stock 243’s that had been ported by Katech. Of course these are a totally different beast. I feel like they made a huge difference. I can’t give you actual numbers because I changed a lot of things at the time of installing the heads. I have a youtube channel it’s moore racing and performance. Check out the chevy Colorado that’s what the heads are in.

[@evcass69]

Are you willing to share the valvetrain component weights and/or head measurements (cc, mcsa, port centerline length, cfm tables, etc)? Are conical/beehive springs an option? Which foundry makes the castings, and where is the metal sourced?

[@andrewcammer2535]

+1 - curious to know the intake valve weight in particular.

[@andrewcammer2535]

Looks nice. What's the intake valve weight?

[@421ssrida]

What about Titanium intake valves? They are great in boosted apps. And you don't have to worry about them getting tuliped like that stainless valves.

[@danielsullivan9865]

What’s the flow numbers and the price? How much power will be increased over ported 317 heads on a 6.0 LS?

[@miguellares7171]

Question how would your heads compare to Frankenstein heads ? Which would be better on a 416 N/A

[@mcternand]

I need those

[@markdonovan9247]

Do you know what they flow?

[@bobbyhuckey5665]

Love all your videos! I do have a question if you don't mind. What is the difference in a 5.3 LM7 2007? I looked up the serial number on the block and that is what I have found. Just curious.

[@baby-sharkgto4902]

A difference in-between what?

[@timweb1510]

@@baby-sharkgto4902 I believe he means the difference in the ls3 title and his lm7 engine

[@bigal878]

Great looking heads. Do you ship to Australia 🇦🇺?

[@baylymiley]

I've got what I think must have been the first sets of these castings, they're BluePrint Engine PS8015 CNC Ported, I found a set of Xceldyne Titanium valves that I'll have to have turned to work, but I'm wondering if I can buy those exhaust valves from you? Are the 8mm x 5.450"?

[@paisley2342]

Looking into these for my LS3. What is the stock chamber size? How much can be milled safely for 93 octane and fairly large 233/253 cam?

[@chandlerlofton6536]

I’ve heard the 11 degree heads wear valve guides?

[@martygrajeda3457]

What is the cost?

[@scotthultin7769]

23👍's up EG thank you for sharing 😮

[@scotthultin7769]

I heard that if you're running a little less spring pressure on the exhaust to get more out of them more horsepower and torque can you agree or disagree

[@scotthultin7769]

The reason I was told this is they said that the exhaust coming around the valve was trying to close the valves for a little less spring pressure will make it easier for the valve to open and let the exhaust out so you gain a little there

[@chrisdavis6500]

Will these fit on a 6.2/lt4??!!

[@bobd9911]

What cc's are the chambers

[@paisley2342]

69cc per website

[@DanaLucas-oi8il]

Were are you all located. Need a 5.3 rebuild

[@adamspencer3620]

Is titanium a option ?

[@jonathanmoore5112]

Will btr shaft mount rockers work with these heads?

[@mrweayoobagggo.3119]

Nope I called & asked him
