Thanks for great prices and options. I think alot of cam only cars with good valve springs should take you up on the bare + valves deal. Is a milled 243 gonna produce the same results as an equal 5.3 casting?

So would they flow better on a 4.030 bore than the 3.905? I've got a stock motor now but building a 408. If I stuck these on my stock shortblock now would they be sufficient for my 408?

If you wanted to get these or our LS6 style heads, we could increase the valve sizes to 2.08"/1.60" at a later date for a minimal charge. PM or give us a call if you have anymore questions.

I love my Patriot heads, havent had a chance to take it to the track yet (damn rain) but I dont think I will be disapointed.... TTT for a great deal & guy to deal with.

243 casting are new GM LS2 castings (05+)
The difference is that welded 6.0 59 cc still keep more PTV clearance to allow bigger cams than if you milled the 243 to achieve 59cc.
I doubt seriously there is a major power difference all components and chamber size being the same, but milled 243's might flow a little less.
In any case, this is a really good deal with Ferrea/dual spring setup.

for example lets say was going to buy a set of 5.3l heads from tsp and use them with a ms3 cam but have to fly cut IF i used your 6.0L heads and had youguys set them up to have the same valve sizes and combustion chamber size would i have to fly cut also would this mean i have a different compression.. and if this is so would i gain more by milling your heads further and still flycutting????
***bare with me im still learning so the Above post might not be 100% logical***

It might even fit PP 59 cc with 2.02/ 1.57 valves ( not sure though)
But with bigger valves, the way to do this is stick the cam in and measure PTV.
No sane sponsor here will give you a definite answer, it will be it "should" but "better measure", which is sound advice when you're playing with cams that size.
