I use forged probe srs flat tops in my 347. One thing I like about them is they have reliefs for TW and inline valve heads. Right now I run TW heads so if I ever wanted to run say a victor jr head, I could fit them too.
A victor jr headed 306 with a good intake like a rpm II you have planned will make very good power. The cam will be very critical. So decide what kinda power you wanna make and how high you wanna shift. You have 4.30 gears so no need to worry about excessive low end torque. I'd build the engine to make power to 7000 rpm. Upgrade your stock rod bolts to good arp's. Or save up a little more and do the 347. It requires the same machine work as a 306.
thanks, I'll look into the 306 project... do you know if it costs a lot of money to just goto 306 ? Please let me know what it requires, and if it is in the budget; I will do that also.

Well, you'd need machining, new pistons, rings, bearings + balancing and labor. Also depends on your area, around by me it costs a lot more, in the middle of no where its a hell of a lot cheaper. I would suggest saving up a little extra and buying a 347 assembly instead of going 306. It will cost more, but make a lot mroe power across the board.

As you can see, things can snowball quick. If you are on a budget and your engine will see less that 5400rpm most of the time, a better choice is Explorer P heads \w 1.7 rockers and intake. You can pick up P heads cheap, get a valve job, springs, rockers, intake elbow, P headers, 65mm TB and for less than $1200 you will be making 280+hp. With a good cam and some port work, 24#, MAF, and custom chip you can get to 300+hp. If you have loads of cash then go for the alum heads. Just remember that many people run out of money and never finish their projects.
