370 hp will put this car solidly into the 13s if you get the weight down below 3600 pounds with the driver installed. so you need basic heads for this.Any head(which is just about any head)that flows over 210 CFM on the intake side. You could build an engine using modified vortecs if aluminum is too pricey? some off brands of aluminum are priced fair,look around your area.
aluminum will also save some weight your car needs to lose.Best time I got from my 1980 was 11.93@111 mph.It had lots left,but I had to sell it when I bought my last house.

Okay after having educated myself I'm looking at the dart heads with 64cc and 180cc intake runners. Those heads have a max lift of .510 so how do I go about finding a cam that matches up well with that? Oh and they will have a matching Intake as that's part of that top end kit

the supplier you are looking at is probably offering springs that are limited to .510 lift.
always use the springs that match the cam

cylinder heads usually come assembled.
The springs have a certain amount of pressure and length that can work with a generic number of lift and rpm.
the bigger the cam,the more spring pressure you need to close the valve and sometimes the spring needs to be longer to accommodate a higher lift cam. A roller cam needs more pressure than a flat tappet cam.
most people that are building street engines are using a flat tappet hydraulic cam that does not require much spring pressure
most people want better heads to make more power?
Most engines that make more power,require better cams that require more spring pressure.
If you buy a decent cam to make power,the cam manufacturer will supply springs that match their cam profile.
DONT: buy a cheap cam
DO: buy a good cam and complete kit
buy a set of heads that match the cam
buy a matching intake and fuel management system,
buy a decent exhaust system.

Okay well I was planning to put in the dart heads and an edelbrock performer rpm can but the heads have a max lift of .510 and that's the max lift of the heads and I was wondering if that would work or do I need to find a smaller cam?

510 is not the max lift of the heads.510 is the max lift of the valve springs.those heads can go 600 lift.

you need the springs from the cam manufacturer.Buy the heads without springs

Building a 355

I have some questions about the stock pistons. You said that .030 is stamped on the top of the pistons correct? Have you looked under the piston for a part number? Look at these websites to compare the pistons to the ones that match yours. Flat top piston - Keith Black KB Performance Pistons KB404-030 - SummitRacing.com. Dished pistons - http://www.summitracing.com/parts/ue...make/chevrolet Dish, with a D-shaped cup - Keith Black KB Performance Pistons KB142-030 - SummitRacing.com. They may not match exactly, they could have 2 or 4 valve reliefs. You have to know the piston head volume so you can order the correct head chamber size. Like I said there should be some numbers on the under-side of the piston. I really like the Dart top end kit. Dart SHP Special High Performance Aluminum Top-End Kits for Chevy 01311132 - SummitRacing.com. You could get up to 500 hp with these heads and the right camshaft.

Yeah I was looking at that kit and wasn't sure wether I wanted 180 or 200 intake runners as I didn't know which would get more power. The pistons I have are flat top pistons with 4 valve reliefs

For a hot street sbc with a 6500 rpm red line (pretty typical) here's a really good set of heads:

JEGS Performance Products 514022 JEGS Small Block Chevy Cylinder Heads

Go with a Edelbrock RPM intake (even a nice used one will work just fine)

and the cam selection will depend on your exact usage and wants.

That combo can't be beaten by the Edelbrock or Dart package.

If you want to go even cheaper the Assault Racing Heads have a chinese head that actually works really well, its a copy of a much more expensive Dart head.

Okay so those jegs heads plus Edelbrock 7101PK Edelbrock Performer RPM Manifolds & Kits for Chevrolet
Is that a decent setup that will have me speeding along and somewhere over 400hp?

depending on the cam you can be WELL over 400hp, could be over 500hp depending on the rest of the combo- but that would be a fairly rowdy engine.

Well the cam that comes with it is an edelbrock performer rpm cam with 308/318 duration and a light of 488/510 with a matching intake and an edelbrock 750 cfm carb plus those heads you suggested
