Good Flowing 5.3 Cylinder Heads for Boost
Getting ready to build a decent 5.3/80mm turbo Mustang and was curious about what aftermarket cylinder head options there are out there for 5.3's I have a sent of 243's that I could rework, but instead of investing in a set of stock cylinder heads I could purchase a set of better flowing aftermarket pieces.

TFS As-Cast 220s might fit if you do a .040" overbore to 3.820" bore.
Otherwise, the TFS 205s are designed for the 5.3L bore and are fully CNC'd and come with PM guides from TFS.
Either has the thicker deck and rolled valve angle.
But a set of TEA or AI ported 243s would be very good as well with LS9 gaskets.

This head only has 1.975 / 1.575 valves however and its a velocity animal with close to 300 CFM through that really small intake valve (meant to work better on the 5.3 liter bore size). Also the exhaust is exceptional as well....240+ CFM through the small exhaust valve.....an E/I ratio of 81%
Boost anyone?
This head would make good power N/A on a 5.3 but be exceptional boosted on the same size engine with the velocity, CFM, and the ratio of intake/exhaust
If anyone is seriously interested shoot me a PM.....I will give you a deal on a set if your going to be featuring the results here and I like the overall game plan and direction of the build!
Catch you guys later

Exhaust Valve Size
Hi Tony, what would you do to increase Exhaust Flow ?
Years age I had Guy create a SBC "turbo" head with a 1.7" exhaust valve/largest port.
Would this be possible with a LS at 3.82 ?
I LOVE the GEN-IV AL LS-5.3 at 3.86" with wall @.120" average.

Out access to such high level.parts and the amazing tuning capabilities from.these newer engine management systems has opened the door to things.ae thought impossible in the past. Nowadays everyone has a 1000hp turbo junkyard ls special for less than 2k$..also people are running numbers thought i.possible in the past have been obliterated we have radial dudes in the..mid 3s. Big.tire.no prep. Door cars in the 3s.

Ls BO 53- 243/799 heads came on every Gen IV 5.3 built. Very common and not expensive.
Under boost, head work is not really necessary. See Richard Holdener's videos on the subject.
You talked much above and really said very little....
