L98 350 Heads, Cam, 305 tpi expermintental build up

First off, you post a search comment and I'll slam your butthole good. I've been here long enough to know that.

With that comment out of the way here is the sitution. I have 350 L98 Heads, paid 100$ bucks for them, thought I could put them to some use.

I spent the weekend helping my friend to dismantle his 350 for a build up and learned alot tearing apart an engine. I have been planning my build up for some time, and I'm not building up a 305.

Aside from the point, my 305 has been rebuilt and is a good learning block to experiment with a few things.

I want to take the L98 350 Heads have them ported, polished, vavle job and decked, I will also have to have my intake shaved as well so it will fit nicely with the new heads.

I've read the facts and opinions on 350 heads on a 305, I know it will lower compression. This is why I am having them shaved a tad bit.

We also know that they will bolt up correctly, but we have all heard about cleance issues. I think this is somethign the machine shop can work out though.

I also have a rather very nice high lift cam for this motor.

My car ran 14.65. All I want to do here is push low 14.2 or so and then I can go find my block for the big toy I want to build.

If I could just get some opinions, and advice about what to look for.

I'm not spending mad cash here, just experimenting. Freebies and Cheapos

I cant remember where I read it but I swear I read that the 350 heads wont work on a 305 because of the valves being spaced too far apart for the 305 bore. I may be wrong and I am no means an expert on this so take what I said lightly because I am not positive.

with the lowered compression that'd be a good canidate for a big shot of the juice.
