Spec, if step 2 is deciding what brand of heads to get, do a lot of research on the ProComp heads (if those are the flebay ones you're eye-balling). Then step 3 will most likely be looking into which brand you should get instead.

 

Are you going with after market heads like Patriot or are you going with the straight up 5.3 truck heads?

 

are u saying procomp are bad?
mostly I was looking to buy used name brand parts because LS1 guys swap out components all the time.
I plan to get ported and polished heads.

 

I've heard more bad than good reviews from owners on ProComp heads pertaining to their quality control. They're made in China, unless that's changed, but I believe they are/were "claiming" they're made in Australia. They can have thinner castings in critical spots, such as around the valve seat area where the valves can hammer the head down. Yet on the other side of the coin, some guys will say theirs are working fine with no problems. That just supports the inconsistencies in q.c., which China doesn't have to conform to. Do an online search, you'll find a lot of bad crap about them. I'd go with a well known name brand, even used/rebuilt. You get what you pay for.

 

when I said ebay I meant I would be looking for a deal on ebay lol. I wouldnt buy some knock off. I had a buddy that got some TSP's off of ebay for 500
