Head/cam PTV question for the guru's ..

Okay , My cam thats in the car is a comp 232/238 .574/.586 and on a 112+4

Okay with that out of the way, ive recently had a chance to buy some Ported 5.3 heads,.. Am i pushing it running these heads without any milling ..Can i just run a slightly thicker head gasket. ?

I dont want to destroy my motor 3-4 months later down the road from adding heads.

Any input is appreciated...

are the heads milled? if not then .040 gasket would work. clay it for peace of mind.

No the heads are not milled.. running a thicker head gasket also raises the CR ?

No way.

If ported those heads have bigger valves, which reduces PTV. Your problem will be on exhaust valve
