If you want to keep the manifolds get the tr cheatr v.3 cam and afr 205 package. The cheatr v.3 should make more power on stack mannies than both the tr224/ tr228 and sound like stock. To be honest I would get a EPS grind before either of those...

403hp through stock manifolds. That's a stick shift car though, but still shows theirs hope even with stock manifolds.

ok i have a set of new prc 2.5 5.3 in my other car . hasnt been started ever and have always wanted to go with a nice set of afrs . its a nitrous motor and im sure the heads would help .
so im going to pull them off that motor use the pushrods and ls7 lifters .
these heads have been milled 35thousants ill be fine with ptv on both the 224r or the 228r cm right ? im planing on using a regular gm mls head gasket .
wait could i re use a set of cometic head gaskets ? they have never been fired but have been torqued , i have gotten mixed comments about this .
and 01ssreda4 im interested in your cam only . let me knw !!
