head question

**MCCs WS6** · 07-31-2007, 12:12 PM

i found someone that is selling a pair or 241 heads that have been ported and polished.. he said it had a 3 angle valve job.. he was asking 500 for them because he was getting a divorce.. and needed the money.. is this too cheap to pay for p&p heads?? what should i look for to make sure they are not defective.. any advice would be great.. thanx for the help

i know that the 243 heads are the ls6 heads, are these ls6 as well just a different casting number?

and too check them out i would ask him to take them to a machine shop and have them checked out, and i would talk to the machinist, just tell him if you are confident you will take them to a shop, and if they come out clean and good you just tell him you will pick up the bill, i think maybe like 50 to 100 bucks to have them thouroughly looked at,

thats just piece of mind you know?

up to you, this is what i did when i bought heads for my sbc, they were afr's.

241 heads came on the corvettes and the 01-02 f-bodies. slightly better than the 853 heads that come on the 99-00 f-bodies.

would anyone know what kinda horse power gains i would get out of p&p heads?? whats a good intake, throttle body , and cam to match up with the p&p'd heads?? thanx

224 or 228 duration, 580s or 590s lift, as for the intake, they are all pretty much the same, and throttle body i dont know, maybe you will be better off getting yours ported and polished.

I wouldn't buy em. Just cause they've been ported by "somebody" doesn't mean they'll make good power. PRC LS6 heads from Texas Speed are proven and only $900 and change. Why go thru all the trouble and money for some heads that may perform good to save $400. Not on my car.

I dont want to hijack this thread but last year I had to replace the engine in my 01 formula and the old engine heads were the #241 castings and I got a replacement engine from a 2000 Z-28 and the engine and heads were casted also #241. Does this mean that the engine I purchased was possibly a newer engine? Is there a block identification number I can find out the year of this engine? Either way it is an ass kicking engine with 57K on the Z-28 odometer.
