Can I use 882 and 993 heads on 307
I have my original 307 sitting in the corner of my garage and I want to rebuild it for fun, but don't want to spend a lot of $$ on this engine. I just installed a trickflow 420 top end kit on the 350 in my 69 camaro, but I have all these parts laying around and figure I could reuse most of this on the 307. The 307 needs a complete rebuild.
So I have one 882 head and one 993 head in excellent shape. I also have a performer cam which I kept the lifters/pushrods/and stamped rockers. I put them in a bag and numbered them so I won't need to break in my cam again. I also have a true double roller timing chain with chrome timing cover, a performer manifold, and performer 600 cfm carb. I also have a stock fuel pump, stock 6.25 harmonic balancer and pointer, stock oil pan and new oil pump, old chrome valve covers etc. This all came off my 350 and has less than 3000 miles. Basically I was going to get another set of heads and rebuild the 307 shortblock, but I can't seem to sell the heads. I figure if I can use them on the 307 provided I change the pistons i could probably rebuild this engine for cheap. Can these heads be used on a 307 or is the 76cc chamber way to big?
