Two SC 61's = trouble

Re: EMS has finally got their 8860 on the market :)
The heads where originally bought and ported for a blown 351/ 427 stroker Capri but the owner or so called buyer didn't want them. He went to Brodex heads. I just happened to be there and bought for new price with roller rockers [Harland Sharp],hardened pushrods[comp cams] etc. They are track heat [better springs] with stage two port. They where 67cc chambers I angle ground them down some, but seems ideal now with the turbo's.They unshrouded the valves even more with the porting..E303's have 498 lft 280/280
220/220 @ 50 110 lob sep which makes them quite lumpy at idle. I had a F303 but was too lumpy, req more revs...Unfortunatly when I machined the heads it machined the O ring off too..Had these heads for closs to 8 years now had no trouble with them. Just make sure the rockers are set up right with correct geometry / pushrod length etc as always...TFS TW have a high chamber so p/v clearance is not an issue, though should always check as the valves are bigger and in different position to std so std valve reliefes are useless.. imo...
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
