882 vs 193 heads . When plants run out of the right parts, they use what they have. The catch with performance engines is you can usually find ready to run, used aftermarket heads for $450-500. I played with 492, 041, 186, 624, 882, 461, 462, 450,193, the list goes on and on and my favorite out of all is the #601 305 head that many machine shops and naysayers said will not breathe on the top and limited rpm potential and ping like crazy. I believe 193's are a swirl port TBI headnext to impossible to port and dont flow for crap. I've seen 300HP short blocks with 340HP pistons. First off 882 castings are the old style "heavy weight", 76cc combustion chamber (port size is in the 160cc range) 350 and some 400 stock cyl heads. I believe that 882's were used for a hsort while on L82's before they switched to the horrible 624 castings624's will crack if you look at them wrong. 94" intake and 1. Stock for stock there would be little if any difference. 500-4,000 max. The 193's are TBI heads (1987-1995) and have intake runners of arund 150cc with swirl port design with a 67cc chamber - basically first generation Vortec. 50" exhaust valves but the 882's are the first of the 'smog' heads, they flow well and are not the 'lighter' castings, but it does have the larger 76cc chambers, which means I will barley break 9:1 compression ratio The 193 heads are not Vor-Tec style heads. 6k miles on the engine and even with only 14. rpm. I'd check around at the boneyards for some Vor-Tecs before I put a lot of money in either of the sets of heads you have. 882s could be called the best of the worst. The 882's arent the greatest head but are the better choice of the 2if they arent cracked. My question is what heads would be better for my car 882 or 193 swirl ports? I hear 882 flow better but have a 70 something cc chamber so it has low compression but 193s have nice torque but suck after 4500rpm but will increase my compression. Both have 1. Good pocket porting can make a set of 882's better. The head that is usually refered to as the "Vortec" is the 1996-1999 with 67cc fast burn chamber. the 624 SMOG era heads? which were lightened / thinned versions of the 882 heads based upon what I've heard I had a set of 624 heads taken off with 14. Granted, they'll be small, like a performer or dart iron eagle 180, but still offer significant improvement over a stock head. They are 64cc chambers, but the swirl ports limit breathing to where they are limited to about 3. My question is what heads would be better for my car 882 or 193 swirl ports? I hear 882 flow better but have a 70 something cc chamber so it has low compression but 193s have nice torque but suck after 4500rpm but will increase my compression. Sometimes with double head gaskets to make them more alike. 6k miles on them, they had a crack in one exhaust seat About a different head on each side: Chevy's came that way from the factory. Are you thinking of the 882 heads vs. As compared performance wise to the stock L-98 cly heads, without seeing the port work and valve job on the 882s you have I can't honestly say. yyzy jynhlwk joui zbeu mhu frra ncdusld mrew avkblxo luxd
