hey guys ive saved up some money and just have an oil issue i posted below but other than that everything works great. im looking to spend some money hear in the next month but im not sure what to spend it on. im just wondering if i got a pair of ls2 heads would they fit on my ls1 block? also what casting number should i be looking for? 243? and also if i get the heads and they fit can i put an LS2 intake on the ls2 heads and make it match up with the rest of my intake? just wondering if anyone has done this or has any advice thanks also curious if this setup would make the performance for the money that id like it to? thanks alot in advance
