No worries. How about you list your current mods including cam spec's and a dyno graph is possible. This site is full of good and bad information but concrete evidence is always the best.

Once I change a few things up I'm going to report back. Hopefully with better results!

SBE w/rod bolts
custom cam
drag race prepped chassis w/ stock suspension(front Afco's/rears stock leaf)
stock 243 heads
custom valvetrain(ti valves,conical springs,lightweight retainers,stock rock.)
American Racing headers [stepped to 2"]
Fast 92/92
vacuum pump
dumps with small mufflers off primaries
T-56 faceplated
c5 rear diff. w/4.10's
adjustable clutch
speed density/AFR~12.5

The valvetrain is unnecessary unless spinning the motor above 7000 rpm consistently. I would do trunion upgrade on stock rockers though.
The cam needs to be spec'd to ones combo and to what the person wants out of the car.
The best thing to do on cam selection is to have a pro like Ed Curtis or Martin spec one out for you based on setup.

Figured I'd update:

I took the FIPK off and installed the FTP 104 lid. Car rips the tires a little in 4th now. Definitely have way more throttle response. Next will be an A/C delete with the CHRS1313 ram air.

So I finally got a chance to talk to Ed @ FowTech.

Special thanks to Dr. Whigham for assisting me

Looks like I'll be saving for some small bore MAST cathedral heads and a rear that will support 4:56s. I guess I can expect to see numbers over 500rwhp if I get true duels also. Time will tell

Thanks again for all the members on Tech that have given me great advice and listened to me over and over again lol

Bring on SPRING!

What do you guys think of the MAST heads? I haven't seen many people using them on here.

Worth the money?

I've seen good results with them but plan well in advance. Hopefully their customer service got better.

They had a serious backlog of LS3 heads. They sold a HELL of a lot more than they intended and got behind, so there was a wait for them.

I got mine in like 5 days. They always answered the phone also when I called, so I had no issues.

MAST has helped me with tech questions very timely, but they also ignored a few e/m's requesting more info on a short block. (416).

MAybe they overlooked it as I'm sure they are MAD BUSY. Maybe they decided to answer e/ms' looking to purchase their 20K engine packages instead.

That right there has always been hit and miss for me. Emails getting answered were few and far between. That's why I just call now.

What's everyones opinion on these heads? Worth the money for my cam...

I think with the heads,bolts, gasket and new injectors I'm around $4200 without labor

I would consider Tony Mamo's new heads as well. They look awesome and have always performed well. His customer service is excellent and will talk with you on the phone about any concerns. I'm sure Ed has worked with AFR's before and these are better. I'd at least compare a few sets of heads before making a final decision.

You are talking about the MAST cathedral port heads and not the MAST LS3 small bore heads, correct? If they are what Ed suggests, and he's going to be the one specing the cam, then I wouldn't second guess it.
