i'm a hot rodder from the old days. engines to me were 350 punched and stroked and supercharged not this nitrous and turbos of today. heads were limited to 2 different ones. i'm not used to all this ls2, ls1 and ls6 stuff. a set of ls1 heads and ls6 block literally fell into my lap and i want to build a toy to **** of the hondas...so i'm looking for a little advice...

LS1 heads flow pretty good (LS6s are better), but there are a ton of aftermarket heads out there that even flow better for around $1000. If money is tight I'd keep them. The block is fine. Good luck

If you're a budget guy get some LS6 heads, if you have cash to spend look for something else like AFRs or one of the other performance heads available. Patriot makes a good cheap LS6 style head with everything for around $1200.

What is the car? How much weight are you looking at? Trans? Gearing? Expectations? A bit more info here would help....

For a point of reference, we have a stock 02 LS1/T56 from a WS6 in our 3300lb 67 Camaro, and it is really fun and impressive to drive. Even stock (LS1 heads on an LS6 block it turned out), this engine is a night and day difference from the 350/4 speed that came out. I would recomend you build what you have, you can always modify later...

LS1 heads flow pretty good, you could deck them a little if you want to get a little more compression, just upgrade the springs so they can handle a little more aggressive cam profile, and there is always a head refreshening you know, a valve job and maybe a port, you definitely have a good setup to start with

+1, thats actually a pretty good foundation, and if you could come up with the stock crank and rods, you could build a pretty strong foundation. pm sent.

ls6 is a good block but if your planning on making horsepower go with a 6.0 block and 6.0 liter heads that block is good up to around 1200hp and does not flex and the heads ported and polished should flow around 225cc

Oh i see...won't take much to **** off hondas, stock ls1 heads aren't bad. What kind of power are you trying to make is the question.
