Default Help with head swap?? Need feedback!!

thanks for your time, but i have a chance to purchase a set of heads they are dart pro 1's ported by texas speed they are 205cc ported and polished. now i have Comp Cams rated at 232/238 .595/.605 lift and a 112 LSA. The pushrods/springs/retainers are all new and rated to handle the lift. that is the only internal work done to my car, will these heads be worth it?? any feedback would be awesome!!!!! thank you again for your time!!

You'll want to know the number so you don't get a nasty surprise. If it's smaller than factory you'll be increasing your compression ratio, if it's larger you'll be decreasing it.

You need to know the combustion chamber size so you can determine what your compression ratio and quench will be, and order the correct thickness head gaskets to get it where you want it.

They are decent heads without porting. If TSP did the porting they are probably pretty good. But beware, I do recall some of the early darts had issues after porting.

Ported correctly they can be a REALLY nice head.

When TSP first started porting these some burned oil really badly. It has been awhile and IDR what the issue ended up being.....

How much are you getting them for? How much flow rate are they rated at? What compression will they bump you to? There are alot of questions.
