I will be tearing down soon for a cam swap. My cam is a TR 231/237/ 592/603 111.5 LSA . I was originally just go cam. But I may pull my heads for lifters, and if I do that I was thinking of doing something with the heads. But I am low on cash. Is it work just having mine ported...Or should I leave them be until I can spend some real money on heads?

 

Try and find a set of used stock 243 castings (LS6).

They should be fairly cheap and flow well for the money.

 

port and mill them a touch if you are on a budget...
