Which Head Gasket?
Which Head Gasket? Also, I emailed TEA and did not get a real definitive answer--said it was up to me. I am going to run S1.5 5.3L TEA heads 2.02/1.55 milled 0.010 w/ a 228/230/571/573 112 comp cam w/ 7.4 pushrods. What kind of head gasket should I run?

If you haven't got the heads yet, I would use Cometic .045 compressed gasket and mill accordingly (for PTV clearance) for desired CR.
To give you an exemple, on my next set up: 347 forged.
5.3L heads, stage 2, milled .020 with an FM 11 cam, Cometic .040 and 2cc valve relief pistons with pistons "out of hole" by .005
That will give me .035 quench.

If you go with a Cometic I would use a .045 , The stock gaskets will work well but the cometics will increase compression and decrease quench. With the closer valve drop of a 5.3 head you must check piston to valve clearence, however I think it should be good with your camshaft.
Thanks Brent and Predator. I mean w/ a 2.02/1.55 valves, 228/230/571/573 on a 112, milled only 0.010, I should be good to go, like Brent said--right! How much more of a compression would the cosmetic give?

just so no one makes fun of you they are "cometic" gaskets not cosmetic... i called them the exact same thing for the longest time...
compression ratio is as much of a set horsepower level I think it goes in percentages.

im just gonna guestimate at about 10 rwhp... for a .5 CR rise in your case...
if you get a bigger cam it may go up to 15 or 20.. like i said its more of a percentage...
I would do it also.. if you dont youll wish you would have
