I don't know for sure, your right measure to be sure. The biggest fear with
this combination is detonation, the cast pistons can't take much. That's why
I recommend keeping the compression ratio low.

Bogie, No brainer, stick a Comp XE268 in there put a 750 Holley on it, due a tune up and stand back.

Which Comp 268, one of these or this one ?

Your budget ~ $1400

If your on that kind of budget get your block bored over ask for specs and buy a STROKER KIT from ebay for around $899 and up! you'll be easily a little over 400hp man!!

Doesn't leave any $$ for heads, cam, rocker arms and push rods.

the $1400 isnt all I plan on spending on the engine that's just all I can spend now. I am willing to spend more for a good set of heads and wait a while about installing them so I can get everything else. I really like the looks of the pro-filer 195cc heads and I have heard alot of good about them. I know with the stock pistons I might not completely reach my goal but what I'm asking would the 195cc/64cc heads cause any problems untill I can upgrade the rotating assembly? I dont care about gas mileage. like I said its just going to be a weekend toy. and I want heads that are capable of more in the futer rather than getting more power now and thats it.

Sounds good!

Do the heads you want and then work around them.
build it as you buy it piece by piece. I do this alot. Make sure you got in mind what you want out of it though. By this I mean fast take off, or capable to run Nitro, or just a driver with around 350hp and up?

Do your research some more after you decide on heads and good luck bro!

Nice heads, besides from being lazy at low RPM on a stock short block, it won't
hurt to run them till you upgrade the bottom end. How much those heads cost?

they will give you a world of difference from the stock heads. you wont loose too much down low (it may be a little soggier than a set of 170-180's). i've never heard bad things about pro-filer, most has be good, so i wont try and sway you away from them. if you get the heads though i wouldn't put them on till you have a different cam and valvetrain to go with them otherwise they will be really soggy.

I agree and because of the low compression go with a relatively small cam,
something like bogie recommended to help avoid poor power at low RPM.
Also go with a thin head gasket to get the compression up and keep the piston
to head clearance ~ 0.040".

ok thats about what I figured. Like I said I want something capable of more later. Would I be better off in the long run to get the 210cc or will the 195cc be better for what I have now and still get me where I want to be later on down the road?

The 195 cc heads you are looking at are good for over 550HP
in excess of 7500 RPM on a good 350 CI short block. Bigger is not
always better.

This car has run 10.60's at 126 MPH with a set of ported Edelbrock performer
heads. 355 CI 11:1 compression flat top pistons, Isky 547-A flat tappet cam,
T350 transmission w a 8" converter and a 456 gear in the rear end.

If you plan on going much faster than this or plan on a big CI engine in a light
weight < 2500 LBS car, get the bigger heads.
