I started putting my spare Jet boat motor together for the season today (.030" over 454) and found a leftover set of really nice Speed Pro domes that have like 5 hours on them in storage, the problem is the heads I have (98cc ovals) will make the CR like 12.7:1 , fine if I want to run alcohol, but I don't.

So I started looking around for some spare heads and found some big chamber peanut ports and another set of closed that need a guide replaced (101cc ovals) and I want to be in the neighborhood of 120cc for a total CR of 10.0:1, oval preffered but not real picky (I always find the throttle resonse and mid range power to be more desireable with oval port stuff  )

So what would you do?

I have enough crap to put together a short block, just don't want to get stuck trying to find some heads...

Looking to trade, swap, buy, sell and then buy to get where I need to be. I will be going to the Good Guys get together in Pleasonton at the end of the month with a bunch of leftover race boat crap that I don't need and may get lucky there, but your input would be appreciated...

I have;

perfect set (still shiney) of Speed Pro p/n L2349-F30 pistons mounted on 3/8" bolted rods ready to rock. (2 bolt block cut to fit these)
built set of  cast #3872702 heads 98cc ovals
trashed set of cast #3964290 heads 101cc ovals (need a guide replaced due to dropped valve)
built set of cast #14092360 heads peanut port unknown cc's (didn't check but they're big)

Also have an Edelbrock performer for the peanuts, also have an OEM cast iron manifold for the peanuts.

I just need this as a back up motor for the jet, may end up putting in the jet this year depending what I find in the 468 in the boat now (a lot of metal in the pan  ).

How does it go again? two steps forward one step back!

Thanks in advanced!

Found a naked set of 120cc open chamber ovals for $50 and they magged good
