I have been so busy with work and had to put this in the back burner for a bit. I got in touch with Tony at Speed Inc once again since they did my 416 stroker short block and will eventually put this motor together. This is the top end that I will be going with as follows:
*Mast LS7 265 medium bore 11 degree cylinder heads milled to 64cc w/ hollow stem intake valves and PAC 1205X valve springs
*Mast LS7 4500 efi single plane w/Accufab 4500 TB
*Custom Bumpstick by none other than Martin@TickPerformance
*Morel 5206
This will be my budget over the Winter. I will post pics as soon as I get them in.
My MAST LS7 265 medium bore heads are finally here. Let me just say, that they are so pretty. And MAST quality control and attention to detail is amazing, second to none in my opinion! Can't wait to see their LS7 4500 EFI intake.
One thing that is amazing about the MAST heads is how every single part of the intake and exhaust ports are CNC'd, as well as the combustion chambers. There isn't a piece that's left untouched. I know a lot of CNC programs leave areas of the heads untouched, which may be by design; that I don't know.

Porting the heads is about correct shapes and sizes. Sometimes the programs don't clean up in spots because of differences in castings. I would take a correct sized runner over a "pretty" runner that the cnc touches everywhere.

Thanks for that explanation. I agree; could care less how they look as long as they perform. Not exactly like any of that's viewable once on the car.
As mentioned, MAST did a great job on these heads down to attention to detail. I can't stop looking at them.LOL. I opted for their hollow stem intake valves. Milled to 64cc.
You'll be deep 9's once everything is sorted out IMO
Bolo,
Do you mind posting the price or how much you paid for the parts and labor. That way this will give us an idea on how much money and overtime shifts we need to do. Lol. But can't wait for dyno #s and video of that bad boy!

All I can say is that the choice of parts for this build are not cheap. And yes, I too, worked some OT in order to get the best parts my money can buy, as I only want to build this motor once.
Today I confirmed the order with Martin@Tick for his custom cam, Morel 5206 lifters, and a set of Cometic head gaskets. I tell you, Martin is something else, he loves what he does, his very knowledgeable and his customer service is admirable to say the least.
