Re: 350 heads
I got these and I am very happy with them. Aluminum would be nice but I really don't want to put a lot of cash into this car.

The only real issue I had was the intake bolts. The intake gasket that came with them was very thick and I did not get much thread engagement. So I ended up getting some some 2 inch bolts from mcmaster and a set of thick washers to have one under each bolt. Both high strength and cheaper than a set from jegs with about 3/8" more thread engagement.

Re: 350 heads
If I had to do it all over again, I would get some aftermarket aluminums. Jegs aluminum sbc heads are just over $1000 a pair, and they're supposed to be the pro-filer castings... really good heads. If you're gonna spend $400-$600 on iron heads, and then you need to change valve springsa nd get them reconditioned etc... sometimes it just makes more sense to get a nice aftermarket head to begin with.

Stuff like this will blow Vortecs out of hte water and make camel hump 350s look like iron dukes.

Why would any sane individual want to do that?

Re: 350 heads
So Trickflow heads are the way to go? And I am the opposite of a hot rodder. I like having the correct motor, tranny and looks.

Re: 350 heads
All the aftermarket sbc heads by major companies are good. As long as it's not "Pro Comp" they're generally great products. AFR's are the most popular these days, but Trickflow, AFR, Brodix, Profiler, and Dart seem to all make good stuff. Avoid Edelbrock and Pro Comp. I dont know that i've ever heard anyone say Trickflow is better than any other head, though. Refer to my chart of sbc head flowrates.

Most of the good aftermarket heads are fairly close to each other.
Then put the LG4 in it.
