mast heads vs trick flow keep reading and really can not get a good true thought. which would work the best for the set up i am trying to do?cathedral low to mid(not really what i think i need) ls3 (no one really say were they are) ls7( for most of the reading are mid to high power makers.were i think i need it). here is what i am trying to do and looking for the pro head builders and real world racers thoughts.this is the combos that i am looking at. spec for the car are 3500lb +/- full out 8th mile race car no restriction other than budget, going to be a carb set up on race fuel.plan to have the red line at 7000 to 75000 max.we trying to put this car into the 6.0 to 6.5 range n/a.but will spray it if we have to to get it there. but want to give it the best chance at it n/a first. its a 408. the bottom in is a 58x Callie's rotating assembly,wiseco +5cc domes(12 to 13 cr), clevite coated main,rods,and cam bearings,10295 oil pump and cr-5 chain and already have a qfx 1050 carb.this is a new build and everything will be bought so the combo can go in any direction at this point.
trick flow...... 245(cathedrals) or genx 255(ls3) or 260
mast.... LS7 265cc 11 Degree 4.000"+ Bore
intakes....... mast ported........supper vic......... Holley 4500.
the heads all run in the 2600.00 to 3000.00 the intake jump around n pricing.the mast is not really in the budget but if needs to be can cut a few corners to make it fit.
thanks for any insight that you give.

Talk to Chris Frank at Frankenstein Racing. He has a TFS cathedral port program for the 408 that will carry to 7500. He also does the All-Pro small bore LS7s which may work. And he has a TFS LS3 port program too. Since he sells all three (plus GM casting programs for all three), he is your best bet. Call him and go over your goals and budget, and he'll put you in the right head.
My take would be the TFS Cathedral program is probably what you want depending on what manifold you select. His TFS program has hit 600rwhp in 402s and 416s several times with small hydraulic rollers. Going to a solid roller, I could see well over 600 in that combo. Of course, the LS7s can easily hit that. The LS3s... I'm not so sure. If I had to choose between a rectangular port LS3 or a raised port LS7, the LS7 wins every time. Of course, if you're on a budget, GM LS3s are hard to beat. But if you have $3k to spend, pretty much any aftermarket casting is available and will do better. But talk to Chris... he knows what each head can do and will steer you to the right place.

Well wanting to stay in a 2600.00 to 3100.00 if possible any more will have to regroup. As I said want to stay n/a but on the heads up week end might have to spray it.if I am high(6.50 +) n/a.

My friend has MAST245 + HOLLEY EFI INTAKE on a 416. About 620 to the wheel. Runs 9s on engine. Thats easily low 6s.
I've got same car with TFS245 + FAST102 on a 416. I should have a comparison in a few weeks.
I have a suspicion the MAST or even LS7 head combo is going to put out more power and beat up on the once excellent TFS head.

Heads for thought... I have used both Mast and Trick flow Gen-x the Mast are about 7/8 inch taller than standard LS heads and have raised intake ports.

Have any links to the 402/408's making 600rwhp?

If you want a set of heads that will put you over your goal, then look no further than these.
