ER is a *****..... No shop or selling of parts or porting but .. .Does things only the Top 1% can do or does. Gives it to me straight no Vaseline. Whether I like it or I don't. No $ involved Darin also.
I ask...I get. No matter the question or head thought about. Chris Frank...we've talked so much and he's created so many versions of LS heads...🤫

I haven seen better Darth than Tony's TFS heads for the the typical guy with one stop shopping for the top end or complete build
GG and stock ls6 heads on a 415 ci made 600+ rwhp DD?....light bulb cut on with me seeing this yrs ago with a plastic intake. A porter can make something out of Nothing.

Im really considering pickn up a set of those porters casting BR7 300s for a future build. But whats the point if only way to get Darins work now is call up 1-800-MAST? Same with Chris Frank, is he gunna just ask that you buy his heads? Or let you send in a set?

You go in with what you got and state what you want. I asked for a bad MF'er and what Darin would do for his own stuff. Did cost 2k+ but we made a head for something it wasn't intended for. Chris Frank the same way... If I call Chris ... And state I want a F710 head for a small bore on par with the RHS Ls7 small bore head he did a CNC program for (back in the day) what u thinks gonna happen with $. I've been with some of these guys since they were porting Factory heads and they like me pushing them or asking. I love cylinder heads so do they, and they always show Love. I figure I'm just better with people if I'm not on Ls1tech ....I've got friends Everywhere in this industry...besides this dude Zach. We friends he's just gotta do 1 or the 2 no harsh feelings.

Those John B heads were worth 5000+ in work 302cc btw...if you didn't know. Reason your not seeing factory Ls7 short blocks with 700rwhp. You may see others with larger builds and compression... They really trying to out do a Ls7 short block and smaller build as a daily. Some on corn. Intake choice really helped. Mast, Holley, SM, intake was so close ...light cut on

Hell Chevelle...knowing the guys you know in the race world a good porter is Common. I fill the same way. Reason in asked GG and Darin to do a newer version Ls7 head test. Was told look at who's winning and has the faster ET's. From both. I ask ?'s about all Porter's and heads and there products VS one another. Generally all in the same sandlot if nothing special is done.

that sounds like a great engine. What do you guys think the idle and street manners would be on something like this? Cam specs?

Those heads can tolerate a lot more camshaft.
If my LS3 stroker engine with 20 degrees of overlap drives smooth down low the same overlap figure with those MMS heads would mean that the engine would drive even smoother again.
I look forward to getting these.
Bortous, if your looking for a Mamo top end, you won’t ever, repeat...ever find a better deal than this.

Jimbo- Richard Holdener took a 408ci and made 626 horsepower at the crank.
240/246 duration cam
AFR 245s out the box
Fast 102mm out the box
11.0 compression
I say bump that compression up to 11.7 or so and let her eat some Scooby snacks
