Getting a set of Sq. Port heads

[MR.hp]

I am going to trade some Old Closed chambered heads I have for a set of 880 Sq. port heads (same as the old 990's) and I am thinking of doing a pump gas 540 or larger BB Chev for the camaro. Race fuel is going to be big buck this year and I like to go fast. This will not cost me that much and I am looing at getting rid of my 406 to fund this project. I ran 11.90 @114 with the little 358 flat top motor so I think 10's will be easy with a 540 or bigger.

Got the heads, Intakes and dominator carbs. So a good shortblock should not set me back too much.

I would but these are free. Besides when I get dome porting them I sohould be able to pick up a few hp's.

I don't but for what I am trading I cannot turn them down, Besides a 540 needs a little help now and then.

Was told by a freind who had some of these, He said a bowl clean up and a good 3 angle valve job really helps these heads out big time. So for free I can't loose, I already have a grinder and seat and valve machine to do this.

Just talked with a guy who has a 10.1 496 sq. port engine in a nova tha the shifts at 5500rpm and has king of a mild setup and runs 9.90's all day with it.
He told me to save my money and do a 496 and my camaro should run low 10's all day.

Could be done as I do have a 4 bolt block that need a bore job. Humm....

468, But it's only a 9 to 1 engine. If it were a 12.1 or better than the Sq. Ports would work. I am now looking at a 496 rotating assy that has good parts and 10.25 comp. and I think I could copy Lingenfelders 496 parts list and have a good combo. John Made 660hp with a Sq. port head engine with a 1050 dominator and street roller cam.

You guys will like this, The dude that traded me heads now wants his 188's back. Seems he said his builder told him he cannot use hardened seats on the 802's. I said Bullshit, you do not need that stuff. So basically I pulled the 802 heads off my 461, ruined the gaskets, did a valve job and spent a week doing this and I was suppost to give them back. I said no way. I am going to build a big cube BB Chev and the heads were the key.

Want to sell the heads if you don't use them, have a friend who needs some square port heads.
