305 buildup from last year. question on the heads the builder used

im writing to anyone that can help me with a question about an old issue that came out. i enjoy this mag because its geared in my opinion to backyard diyers, and im a little stumped about an article between june and august of 2008. there was a guy who did a buildup of a 305 chevy and made 364 horses. my question is how did he put those aluminum heads with 2.00 inch intake and 1.55 exhaust on such a small bore. im hearing from the tech guys at summit racing that they will hit the pistons and the largest you can run are 1.94 and 1.50. i know most people dont care about 305s because of the bore situation but i already rebuilt it and i dont have the time to do it on a 350. did the builder use those heads just to see how much power he could make not caring if it would be reliable. i just need to know if i can use those heads because nowadays i cant blow 1350.00 just to find out theyll collect dust. any help will be appreciated. ps i finally subscribed, man thats way cheaper that newstands cost.thanks  

I would not recommend using heads with 2.00" intake valves due to clearance issues and valve shrouding which can cause a lose in power I do not recommend going larger than A 1.94 intake valve on a 305 and I have built a few with great results.

any thing else just ask

I am running a 305 in my 84 chevy truck but im not sure what all I got a friend of my dads had a truck which im strpping for what I want off of it I am running a 700R4 and man it has some balls behind it I have never felt the reaction out of this truck like I do now. The sqat is unbelieveable in the ass end of the truck I have a post on here trying to find out about what type of hp im making but the cam I have is meant for a 350 but it fits in perfect and have not any problems and it is either a 540 or 454 series cam and it came out of a dirt track motor. But Poniac 4 if you can help me that would be great. Thanks  

All small block chevy cams are interchangeable what brand and what is the part number of the cam and what else do you need to know.

Also for a HP rating I need to know the complete specs of the engine.

Chevy small block, generation one, cams are interchangeable...but don't the roller cams run different distributor gear material, that can chew up a softer, non-roller cam distributor gear?  Or is that just on Ford's 5.0?  

Yes with the roller cam you need a different distributor gear.
