Im in the process of building a 402 motor and im wanting to know what the absolute best heads are, iv been looking at...i have a 102 fast as of now and my car is a lightweight auto

-TEA trickflow 245
-TEA trickflow 235
-MAST motorsports

Price is not a concern, I race my car a TON so i want the best/most powerful i can get.

I have looked into both the trickflows but i really dont know what MAST has to offer. im thinking im staying around 11.5 CR for 93 since i do drive my car. But im not afraid of "street maners" as some call it because its not a daily...thanks

You say your building a 402 so you only have a 4"bore right? Better check those Trick Flow heads for their minimum bore required.I believe the 235's require a 4.03" bore and the 245's bigger yet.Those heads have bigger valves so it might be a problem but it could be that they fit but aren't recommended because of valve schrouding.A ls7 type head would be good but it will have to be a small bore version like zglass has.

I run the Mast black label heads. My bore is 4.125 so you need the small bore version. Check out Mastmotorsports.com

Can't beat ported Ls3's for the money. LPE has theirs for 1500 shipped and assembled lol. Hard to pass that up.

if price isn't an option, I'd agree with djfury, mast or allpro

What style fast 102 do you have (LS1/LS2, LS3, or LS7)? You'll want a set of heads that match or you'll be needing a new intake.

Bang for the buck I would say TFS 245's and just guessing... The would best fit your application.

I have a cathedral port 102 ported by tony mamo, ill have it portmatched to a set of heads i get if i stay cathedral...so i thought MAST and ALLPRO were the same??? so how are mast better than trickflow i called mast once and asked for their flow numbers and looked on TEA website and the trickflows flowed better (they say)....

what mast would i get what are they called?

I would not get the mast. There are a few issues that you have to address that IMO should not need to be addressed.

My vote so far and every time is Trick Flow. Although a 245 head would be a bit large, the 225 or 235 would be the best bet. If you want even more out of them, I am sure TEA could spruce them up a bit more for you.

I just called allpro and there "DRAGPORT" heads is what we discussed

they are flowing 355 at .600
and on exhaust 248 at .600

they have a 2.125 intake valve and a 1.625 exhaust



then i looked at the TEA Trickflow 235s and they are flowing

343 intake
276 exhaust with 2.080 intake and 1.600 exhaust valves



it looks like the trickflows are smaller valves and flowing around the same numbers on intake and better on exhaust...with a smaller valve which would probably be better on a 4in. bore

Are for ls2 the small bores are for ls1...
Designed for any new Gen IV short-block with 4.000" bore or larger

• The 6-Bolt design is compatible with GM LSX and World LSX blocks
• Accepts Gen IV LS3 valvetrain and intake manifolds.
• Uses a 2.165" intake valve and 1.600" exhaust valve
• Has a 256cc intake port
• Has a 69cc combustion chamber standard
• Has a deck thickness of .750"

Each Mast Black Label cylinder head assembly includes:

• A fully CNC machined Mast Black Label aluminum cylinder head
• Mast nitrided & micro finished .650 lift beehive valve spring

Then get the hollow steam SS intakes upgrade, get the 6 bolts head even if you are not using them, cost is the same, and are further re-enforced, by the added busses, and have better resale value, then if you still have the block outside, have some one weld the receiver busses, on the out side of the block to bolt the 5th...you'l be glad you did..

Quite a bit longer spark plugs wires, like going to at least the truck style MSDs. Then there is the problem of their holes in the heads that line up with the stands on the intakes are too small and you have to grind all the stands off save for the 2 metal ones. They work.

There are a few others, but those are the biggest 2.
