wat to do with 243 heads?

[chvy=power]

So i just bought a set of 243 heads and i was wondering if i should run them as is or have them worked a little bit (ported,polished, shaved etc.). I'm running a 220/220 .551 112 cam and ls6 intake but i dont want the heads to flow too much... and won't these heads stock lower my c/r since they have a larger combustion chamber? I haven't really dealt much with heads and what not so any advice is much appreciated!

Yes they will drop your c.r. You'd have to shave .020-.030" off to get back to your stock c.r. if my numbers are correct. if your considering getting them ported I'd do it now, otherwise you'll regret it later. You can also look into a thinner head gasket to get some of that compression back

where did you happen to find the heads and how much did you get them for if you dont mind me asking. im on the search for a set myself.

on a 5.3, 243's will lower compression quite a bit. If you're staying N/A, i'd stick with worked 862's or some patriot heads

i got a set of 799's from this place http://www.jakesperformance.com/Home_Page.html for $500. I don't see any engine parts on their page anymore but it might be worth a call

If you're paying to get your 862s worked, why not just pay for work on some 243s and have them milled and a 3 angle job? You'd spend a couple hundred more but you'd have much better flowing heads. They put 243s on the NNBS for a reason... they're nice.

Get a port and polish job done on the 243's. Mill them 0.030 and have your compression back. Put a set of LS7 lifters in and use 7.40 pushrods. Done deal...
