GREETINGS, I have an L24 head and an L28 block both stock, my question is, what are the odds of running this configuration can I get more power better compression ect.. by running this or is better by keeping L24 head/block or the L28 head/block configuration. thank you

The cylinder head from an L24 would have smaller intake and exhaust valves than a cylinder head from an L28. Significant machine work ($) would be required to install larger (L28-sized)valves in the head from an L24. If done, you could probably get more power at a higher compression, but the cost to do so may be a bit high.

The first thing to find out is what head you have from the L24 and what head from the L28. Early L24's came with E-31 head, thenthere were TWO varieties of E88 head (only the early one is desirable).

I don't know the specifics of L28 engines so maybe some one else can chime in or check www.Zhome.com for more info on the different heads found on L28 motors.

There are few differnt types of L28 Heads...
